I was very similar to you. there is nothing wrong with staying in an informal post bac... try to take some upper level bio classes also, maintaining as close to a 4.0 as possible.
Though when i talked to Buffalo i was told a Masters degree is looked upon favorably. the way i have viewed Masters programs is simple and in this order.
1) Masters with link to at least 1 dental school (UMDNJ, Boston, Tufts, NOVA, Midwestern) these are all great examples
2) non linked Masters in oral biology or similar is equivalent to Masters from any good 4 year university (Barry, state schools, ect.) there is some debate if Barry still has links to NOVA and i do not know.
3) informal post bacc with heavy upper level sciences...
A good rule a thumb floating on SDN about post graduate work is if you do not have the pre-reqs informal is the best direction for cost and flexibility in what classes you take (this is what i did for 56 credits) that you can gear toured the schools you want to apply to. while if you have your pre-reqs already and a low GPA it is good to prove handling a rigid course load with the masters programs (i will start a one year master at my state school this august, my application year per buffalo insight and loans i need) grants, school loans will not touch you without being matriculated they will have to be private loans or your savings.
either way it is best to maintain at least 12 credits but more may prove your ability better, high GPA is more important then high credit hours, and all this info is just opinions from myself and a few others from sdn...
good luck
