Project: What to do with my 6 Speed rear derailleur?

I have a 20 year old Univega Viva Sport road bike that I would like to overhaul into an urban commuter. The components are shimano 105. The rear derailleur is a 6 speed and the shifters downtube. I would like to but a flat bar (or something with a slight rise) in place of the drops and get some nice shifters, preferably thumb or trigger. Maybe turn it into a single front gear because the one I have is always getting mashed being parked on the street and being I don't really need all those gears for my commute. (checked out the "Does anyone else hate front derailleurs" and noted some tips).

Anyone have any suggestions?
Can I find decent thumb or trigger shifters for 6 speed?
Can I fit a 8 or 9 speed in the place of my 6?
If I upgrade what derailleurs are favorites? I would want something that can take a beating.

Check with the folks over in the C&V forum for suggestions too... and don't let anyone talk you into getting rid of your older bike "just because". I commute every day on a Trek 520 that I bought brand new in 1983.

As far as changing the cluster to one with more gears:
I changed my 6 speed cluster out with a 7 speed freewheel without changes other than derailleur adjustment. This is especially easy if your shifters are friction shifters... and I'd think about keeping those downtube shifters too... you can't get much more bulletproof than downtube friction shifters. They just never seem to break.

Oh yeah... if you upgrade those old 105 components... send me your old ones! In other words... I'd keep running those puppies unless you have a specific reason not to.

Enjoy your commute... it's especially nice to commute on a bike that you know intimately.

I'll keep as much as I can. Being that I want to park it on the street in NYC I don't want to spend too much. But I do want to get the shifters closer to my hands, don't really need more gears. I shift gears a lot, maybe more than I need to, taking off from all those lights faster than the cabs then kicking it into high gear to keep up with them is really nice. Don't want to do that with my hand on the downtube. Anyone out there have a six speed set up with shifters on the bars?
