Obviously you'll need and 8 speed shifter for an 8 speed cassette, but a 7, 8 or 9 speed chain will be fine. Although, if you're buying new, you'll have more choice if you buy an 9 speed cassette, shifters and chain.

The difference between 8,9 and 10 speed chainsets is marketing. Any chain will work fine on them.

actually 10 speed Shimano chains are narrower than 8/9 speed ones, you will likely have poor shifting performance if you try to mix.

8/9 speed gear is mostly interchangeable assuming you stay with the same brand (sram and Shimano don't tend to play well together as far as mixing shifters and mechs IIRC).

SRAM chains, chainrings and cassettes are interchangeable with Shimano 8/9 speed.

Yes, but any chainset / chain combination is OK. All chainrings are the same thickness in recent years - the only difference is the number painted on the ring.

There are a few 7 speed chainsets where a narrower chain can jam between the rings.

That's good to know, because 9 speed chainsets seem to be disappearing fast. Have a look at CRC or Wiggle, lots of 1, 2 or 3x10 chainsets and only a handful of 9 speed. :shock:
