>>Melamine is not carried in this area at all...
Have you looked at melamine shelving? That works very well. You should also call cabinet shops.
>>I just have not had alot of free time/money to start. so I am oging to use 12 X 12 red oak boards as the shelfe part
You don't have a lot of money and are going to use oak? That sounds very expensive to me.
The problem with using plywood or real wood is that they will expand and contract with seasonal changes. Unless you allow your oak boards to acclimate for an extended period in your herp room you will likely have issues. This is very important to keep the boxes secure and sliding well.
I believe birch laminated plywood would be a much better choice than oak boards. It's smoother, which is very important to racks and won't be as susceptible to expansion/contraction.
>>and was wondering what kind of paint woudl be best.
I would use a wipe on, oil-based polyurethane.
