Is this the right order?
It depends on what do you wanna do 
!
You can Bind everywhere but before glBegin()
You can select different color for each vertex
glColor
glNormal
glTexCoord (in the order you want but before glVertex)
glVertex
or you can specify color before glBegin (every vertex will use that color)
For the transformations it's standard to Rotate and Translate so you must call
glTranslate
glRotate

Hmm thanks, but I heard you''re supposed to rotate before you translate...
Anyone know for sure?
Thanks

No, order is very important and you need to rotate and then translate so
glTranslate
glRotate
but you must read from bottom to top !

It depends on what kind of movement you want. Translating 10 units back and rotating 90 degrees will move the object back and rotate it there. Doing things in the reverse order will rotate the object 90 degrees and move it to the left. Sorry if that wasn''t too clear. N E ways, experiment with it and see which order works for what you need.

Probably, your confusion is about this:
say, you have a cylinder standing straight up with y - axis running vertically through it''s center. Now, you want this cylinder to rotate 90 deg. around the y-axis. then what you do is, bring the cylinder back to the origin , rotate it along the y- axis and translate it back to where it was.
So this order of Translate, Rotate and Translate must be followed if you want to rotate an object around one of it''s own axis and not around one of the world axis.
Hope that clears it.
