Excellent first go around! I have done mobility stuff with bands and foam rolling and even movemtn stuff, but as you mention it got to be too much, so I whittled it down. Sacrificed the foam rolling and movement stuff. Now I'm cutting the band stuff back and bringing back the foam roller as I miss that the most I think and it was certainly stupid to drop it because of laziness.
I do think mobility stuff is important in genneral as it does help you perform the lifts. I know there is an argument about the lifts themselves being enough mobility work as long as you perfrom the lifts correctly, but I have my doubts about that.

Hack away at anything which isn't essential. Do what you love, and do it often. Fazc.
Everything competes for recovery so more assistance is not always the best idea. miked96
