2001 Hyundai Accent Burning oil

Whenever I go to take off from a red light or a stop sign, my car accelerates very poorly most of the time, and once I get going, I can smell oil burning.

The left front brake caliper sticks (doesn't release good).
My check engine codes are 0136, 0141 (rear o2 sensor codes), and 1529 (not sure what that one is)

I was also told my oil pan was leaking, despite never seeing any drips on the ground anywhere I park. Can it leak without leaving any marks on the ground?

I was just wondering what could be going on causing it to burn oil like that, and what I would need to buy to replace.

Thanks,
Gerald
