I'm planning on replacing my Crank and BB on my '02 Fuel 80. What would be a good replacement triple crank and BB? The chainrings are worn and it's time to ditch the entire thing. Do I need to stick with the 42-32-22? most of the crank assemblies I see online are 44-32-22?
Give me 2 or 3 suggestions for under $175.00.
Thanks

The 44 big ring should work no problem, but if your front derailleur is set close to the current 42 tooth big ring, you'll have to slide your derailleur up on the seattube to give clearance for the larger ring. Moving the derailleur up will slacken your cable, so you'll need to loosen the cable at the derailleur and pull it tight again after moving the derailleur.

Your bike probably has the separate bottom bracket/arms. Suggest going to the newer external bearing designs. Easier to install, and easy to replace bearings if you ever need to. You can get Shimano LX/SLX/ Raceface Evolve for under $175:
Here's some Ebay buy it nows:

Do I need to know anything about the length and sizing? or will the Race Face (or Truvativ, Shimano) all fit or have the shims needed to make it happen?
My bike is pretty much NORMAL, right?

Will I need to replace the chain too for a 44 tooth outer? I just replaced the cassette and the chain 50 miles ago. I guess this is a piece meal drive train replacement, but it just happened that way :???:

Regarding crank arm length, you'll find these in various lengths, the most popular would be 175mm and 170mm. Check to see what your current crank arms are (usually it's stamped on the back side of the arm near where the pedal shaft goes thru, like in one of the pics in the first ebay link I provided). Small frame bikes sometimes come with 170mm, seems like most medium/large/extra large come with 175mm.

The external bearing cranks will fit either 68mm or 73mm bottom bracket frame shell widths. Use one spacer on the drive side bearing for 73mm frame shell. Use 2 on drive side, one on none drive side for 68mm. The spacers I'm talking about are the 3 rings at the bottom of this pic:

When you put on the new chain, did you cut it to shorten it? If you did and shortened it so it was stretched straight when on big cassette cog and your 42 front ring, then the chain would be too short...but you're not supposed to 'cross-chain' to big/big anyway.
