I use a marker on pipe more often because a pencil mark can too hard to locate in dim lighting.

For cutting there was another thread about this. Myself most metal saws will work. Not a tubing cutter person but it still has it's use.

For small pipe I like the reamer screw driver. I see more guys just use Chanel Locks.

Maybe you could list some pipe bending formulas.

The Bendfield book is also a good place to learn.
