Since this tank is frameless, you'll want the center of the tank to "float". The reason being that, under pressure, the glass will push down against the floor support, with the floor support exerting an equal amount of pressure back against the glass (physics, lol). If there's ANY kind of uneveness against the glass (eg. a knot area in the plywood), it's going to create different areas of pressure; foam will only provide a marginal buffer against this. Imagine pushing the end of a 2x4 against the center of the front panel, it'll just break. The same applies to your bottom panel, except tenfold since that's where all of the weight is concentrated.
For this reason, Oceanic will not warrantee cracked tanks that are not put on Oceanic stands. These stands support only the outside edges of the tank, thus, floating the center. Edit: you're going to want to go back to Home Depot and pick up some of the 3/4" hard foam insulation sheets for this. Soft foam is just asking for it...

OK, thanks Albert ill do that today.
How much of the center do I cut out so it can float? Or I guess it would be easier to ask how wide should each side of the foam be after I have cut out the center? Thanks Albert.

You only need 4"-6" around the perimeter of the tank. Just make sure it's a pretty stiff insulating foam.

Oh yeah, Keith, you might want to put the tank on it's back and paint the bottom of it white prior to actually doing anything with it. If you don't, you're going to end up with that disgusting "refracted ugh" look that a lot of BB tanks have.
