I put some of this information in your previous thread where you first asked about them (Raised Spindles...
). However, I'll copy it here as well:
I've never seen quantifiable data as to what the different grades of bars actually correlate too - other than increased stiffness.
'Best' to 'Worst': 1,B then F type.

Probably +/- $250ish for the pair.
No, they don't have to be installed by a shop - but there is a huge amount of pressure on them, so you have to be careful when unloading them. They make a fancy 'torsion bar removal tool', but I know many guys have used a puller or even a c-clamp to make it happen.
Random picture of the tool:
