Even after baking, you still gain room after about 10 or more hours of hard skating as the foams compress (I'd say about another quarter size). So, what may feel like the right size now, may be a little roomy after some time. The only way you'll know is by skating on them and seeing - that's why the 30 day satisfaction guarantee on the True skates was great when they first came out. I doubt that'll apply to clearance skates, but at the prices they're going at, it's worth the gamble and you'd probably be able to resell them if necessary without losing too much money if they end up being too big.
The foams that take up space above the toe box are called powerfoot inserts. With that said, adjusting the tongue as low as it can go in the toe box is a good, free first step that you can try to see if that helps.
