Jiffy stand will be fine - you're lifting rear fender up by installing taller shocks - won't be affecting ground clearance. Your ride will be much improved though!
Yes it will raise your bike...the top of the shock determines the height of the bike....the bottom of the shock is the fixed position...and yes you will be ok...the bike will go over a little further, but it will be fine.

No, it raises the ground clearance. The entire frame is raised up when using longer shocks. Since the bottom of the engine cradle is part of the frame (and the lowest hard point on the bike), it will be higher. It will also affect steering performance (changes rake and trail), so be careful until you get used to it.
