MTB Changing SR Cranks to Shimano LX M580
I have a 2001 Giant Rincon MTB with SR cranks that are in serious need of replacement. The rings are rivited so the whole crank needs to go due to 5 years of wear. Currently, these cranks are sq taper and the BB is 68x122.5mm.
What I want to know is can I put LX M580 cranks on my bike with no major effect to the rest of my drive train? Most of the info I read on cranks say that LX cranks are 9sp - can I use them with a 7 speed freewheel setup? I have already replaced the freewheel, and I have yet to buy a chain but I will do that as well.
My derailleurs are working fine so I don't want to change them - however my Fr Der is e-type. Can I upgrade cranks to LX M580 (I believe this is the crank with intergrated BB) How does the spindle length effect my chainline?
Would I have to change anything else on my bike?
Can anyone suggest alternate cranks (FSA, Truvativ etc) that may be better for me in the same price range of under $200US.

Thank you for the assurance. I may not buy that specific model LX but I will be sure to increase my value and performance with whatever brand I buy. My current ring set is 24/34/42 - can I deviate from that at all when I get new?
What type of BB spline is considered most current/efficient? ISIS, Splined, Octalink, so many terms - I get confused.
Truvativ seees popular for DH and FSA for racing. Any clarity to offer - or is it a design preference in most cases?
