If I use proactive dark spot corrector and retin a (tretinoin) 0.25 can it help with my acne scars?

No. Neither will touch actual depressed scars, not can anything else. At best, you can hide your hyperpigmented lesions and even this is likely not to be very successful. Get your active disease under control, and if you wish, get seen by a dermatologist or plastic surgeon who can deal with the scars using a filler, laser or microsurgery.
