Unfortunately, although the paint was good on 93 Konas, it was the last year when the frames were not 'suspension-adjusted'. Which means that if you wanted to fit a suspension fork, any year from 1994 onwards would have been better!
Fortunately the fork on the bike is the lighter (and classic) triple-butted form of the P2, which is the perfect match for the frame and not at all hard on the hands. My advice would be to see how you go with the P2s for a while - I'm not minimising your injuries, but it's inevitable that you'll find it punishing to begin with after such a long layoff.
But then if in the end you decide you have to have suspension, I would advise selling that bike and buying a slightly later one instead. OK, it's a bit of trouble, but the cost wouldn't be much different. Lava Domes make decent money quite easily, because there's always somebody out there thinking 'damn, I wish I'd never sold my Lava Dome'.
Last thing is, are you sure you need a new hub? That's a pile of trouble and expense - wouldn't new grease and bearings do the trick? There's a few people from Brighton on here (but I'm from Hove, actually) that could maybe help you out if any help needed.
