This forum has been a lot of help, and I thank you all soo much, so my next post here is some questions.  More of a checklist.  What is the best/strongest parts for the following:

Wheels (complete, no assembly required, and since I am a big guy, something very strong).
Brakes (front and back)
Levers
Tires
Seat (I have a KHE seatpost, and the seat I have will not fit, found it out later)
Pegs
3-Piece Cranks (the ones I bought (Demolition) do not seem to fit the KHE Frame, nor by Tree Bicycle Co. Sprocket).

Thanks everyone!

Wheels: flatlfuel has some great 48h wheelsets on special now.
Brakes: Odyssey lever without a doubt. You can replace the nut if it strips out unlike the tech 77. get the diacompe 990 if you're on a budget. Great stopping power.
Tires: Primo wall are great but a bit heavy, so maybe frequency G's?
Seat: Do you have a pivotal seat or...? Maybe the rails on your seat need some clamping together before they'll fit the seat post guts. More info needed here.
Pegs: what would you prefer? A larger diameter seems more comfy to stand on.
Cranks: Do you have the wrong size bottom bracket (BB)? They'll fit once you get that sorted out.
Sprocket: do you have the tree spline drive sprocket that is incompatible with your current spindle? Maybe you're just short the correct spacer? Micro-drive maybe?

Hope that helps!
