Dunno about the Sat-30 bridge, but the Lo TRS 2 isn't that great a Floyd. The Edge and Low Pro Edge are Ibanez's high quality Floyds, the TRS is a bit bargain basement.

Jumbo and medium are just different sizes of frets. Play some guitars with different sized frets and see which you prefer the feel of.

The last two... well, a 22-fret neck has 22 frets, and a 24-fret neck has 24 frets. What don't you get about that? Some people will tell you that 24-fret necks are inferior because "the neck pickup should be where the 24th fret is to pick up harmonics". Ignore them; they are weak-minded (not to mention fundamentally incorrect).

It comes down to whether you'll really need those 2 extra notes that a 24-fret guitar will give you.
