Chain rub against inside of derailer
When I'm in the small chain ring and biggest cog the chain rubs against the inside of the front derailer. Even in the 2nd biggest cog theres a litte rub. What kind of adjustments do I need to do to get rid of that?

I'm no expert, but:
1) try loosening cable tension by turning the front d' barrel adjuster clockwise a bit (as seen from above). Be careful and note how much you turned it in case you need to get back to that point.
2) If that doesn't do it, adjust the lower limit screw on the front d. Usually it's inboard. Turn it clockwise 1/4 turn at a time. That should allow the front d' to move inboard.
Note: you should also look to make sure the front d' is exactly in line with your chainrings. If it's not, you may need to loosen the holder and rotate it a bit.
HTH.

Low limit screw about a 1/4 turn clockwise. If that doesn't do it, turn it a little more. Just do it a little at a time. The low limit screw should be the closest to the frame.
