Well I did the math and the derailleur I have has a max chain wrap of 26 teeth. If I went with a 48x34 compact double my chain wrap would be 28. It also means that if I went with a megarange 7 speed freewheel (14x34) the chain wrap would be 30 with the current cranks. It sounds like no matter what I would have to buy another rear derailleur (which isn't the end of the world) but when I decide to spend the money, I didn't want to completely overhaul this thing. I like this bike but I hate to spend hundreds of dollars on an old bike.
