Midscreen, Noob doesn't really have high damaging combos that don't use Meter. Here some some BnBs that I use Midscreen:
Back 1, 2, 1, 4 xx Teleport (Can be EX'd)
Back 1, 2, 1 xx Fireball (Can be EX'd)
Back 1, 2, 1, 4 xx Running Clone (Can be EX'd)
2, 1, 2 xx Teleport
2, 1, 2 xx Fireball
Now, you can use meter for his midscreen combos, but in my opinion, Noob needs to save the meter for the corner, since that is where he shines, or breakers, since he's a zoning character and if pressure gets put on him and he doesn't have access to a Breaker, then it's going to be hell getting the opponent off of you, and you just might lose because of that.
