new drivetrain for the green tractor

Devout Dirtbag
excitement at receiving a near mint raceface crankset had me running to my LBS... my purely recreational use of this machine over the last decade has left me both clueless and tool-less to put these on. this bike has never been in a shop before.

a favorable experience at the LBS! everything is working sweetly and I love the new ratios. the LBS was, of course, unprepared to offer me any boutique or old school parts. what got installed was:

shimano CS-HG41-7ac cassette
shimano HG-50 chain
shimano UN-26 68x113 bb (my nice bb was too long)

again, being out of the parts buying for sometime i'd appreciate any advice on upgrades for these items. I see a NOS shimano UN73 on ebay? whats the standard performance chain for a 7 speed these days?

appreciate any insight.

Nice. Don't think I have seen that Brodie on here before. SRAM chains will do earlier 8 speed chains had a problem but they have since sorted it out.
