my answer is gonna be 3 parts:

1. ohlins 2-2b shocks are 12'' shocks but with the sag set, actually sit a little lower, but yet still have a decent amount of stroke for comfort.
2. being an 06, the most common way to lower the front would be the progressive mono shocks. lot of folks like them, i have never used them.
3. being an experienced rider, you do not have to 'flat foot'. i'm just shy of 5'4'', and i've never been able to flat foot any of my touring bikes. you just really have to be cognizant of your surroundings. don't park nose down in a parking space. even 'regular' height guys can have problems with that. to give you a frame of reference, the ultra low model has 12'' shocks as opposed to the stock 13'', and the front forks are lowered 1'' as well (which you could achieve with the mono shock) if you wanted to go lower than that, you would be giving up a lot of your lean angle. before you go to such drastic measures, try it with a conservative drop and see how you like it.

ok, i lied, 4 parts. 4. your wife is tall (well compared to us, and for a woman). let her be your outriggers when you come to a stop. you just keep your feet on the floorboards

 

I don't think lowering is bad. But not sure about 3". I have concours, which is really tall. I am more careful about wear I park. I also don't think you need to be flat footed on both feet.

You should lower the front. My 01 came with a lowering kit in rear and standard shock.That is supposed to be the wrong way to do it. It does ride rough, but it has 77k. I That does lower it alot. My 07 I went with progressive 440s and maybe 12.5ss. Better shocks then factory will give you a good performance with less travel. But don't go to short. Progress ive salesman told me 12.5? at Sturgis. E-mail the company ask what the lowest you can go without losing comfort. See what they say.

A corbin seat will give you a narrower stance.

Lower it to much and you will lose comfort.

I do plan on updating the front end at some point. Salesman did tell me it is best to do them together. Over 100k without though. But I am not a real aggressive rider.

 

I just picked up a '10 Street Glide and being 5' 4" had exactly the same issues. I got a Super Reach seat which moves me forward and down. Some complain it squashes the 'nads but while it's definitely a snug cradling I'm okay with it. I also had the front suspension lowered 1". The Street Glide already comes about an inch lower than other touring models so they didn't do anything more in the rear. I was a little disappointed but thought I'd give it a try.

I found parking and specifically reversing was tough on tip toes. Since my previous Softail had Shotgun air shocks I looked for the same for the Street Glide and came up with Legend Air-A adjustable air shocks. I HAD to have them, and now I do. Essentially I slam it flat when parking and can now just about flat foot. When riding I inflate to about 70 PSI and still have a low but comfortable ride. I can easily adjust on the fly if I feel like I'd like more air.

LOVE them!!!! And the slammed look when parked looks awesome too!

 

if you get the horned shaved by a good seat person (Mean City Cycle or equivilant) it will allow you some more leg room without giving up any comfort, and actually they can make it even more comfortable if you want. I am a little taller then you but I found stock seat made me uncomfortable, once I had horn shaved and a couple other things but mainly horned shaved it made me way more comfortable with the bike. I didn't want to lower unless I had to since I knew it would sacrifice some ride quality. With your height I would think you will have to lower also.

 

Lowering a 2006 3" and still having any ride or handing left is a tall order.

If you would get a 2009 up...you can buy a drop seat frame section, that lowers it 3.5 inches in the drivers seat area only...leaving the suspension untouched..that is the way to go.

 

 

I'm only an inch taller than you, and I've had tall girlfriends/passengers. There really isn't anything wrong with letting them hold the bike up. Other than the times you forget to put your feet down, they aren't on the bike, and you fall over. Not that I ever did that!

I've got what may be a reduced reach Comfort Stitch seat myself. I've tried several other seats, including the Corbin Close, a newer reduced reach seat, and one or two others. I keep coming back to that old Comfort Stitch. I do stuff a bottle in the split as that helps push me a little bit forward on the eat.

I played with lowering shocks and not. I like the reduction in my height, don't like the reduction in ride quality though. I also don't like the reduction in ground clearance. In the end, I ended up at stock height with the suspension.

Buying a reverse gear was the best choice I made. I can keep the bike upright just fine on sorta tippy toes. Just can't push it around that way. With the reverse gear, I can walk it backwards out of anything. So I don't fret where I park or stop.

 

Paying attention to where you park helps. Unless walking an extra 20 feet is a big deal.
