ad441- if you're gears are working OK right now i'd not bother upgrading unless you want to go to indexed - in which case late 6 - but most likely 7 or 8 speed is in order. but unless you have shimano style braze-ons on the frame you'l have trouble fitting- it's very rare to find a band on that will take indexed downtube shifters. i'd start by looking for the shifters and then get the rest to suit whatever speed shifters you can get hold of. - bar end shifters are good alternative if you can get / afford them (they always seem to going for a lot)
exage, and rx100 (actually un painted 105sc) are usually good value for money 7/8 speed stuff as they're under rated , nothing swanky but very serviceable for get-around / touring bike.
something like exage trail (or exage LX) triple 28/38/48 with front and rear mech to suit should be less than 25 gbp in good nick - early MTB deore is also good. mich do a nice long reach pair of calipers for 19.99 on Eaby -
