Both of those boards are definitely RED oak.
As far as clamps go, Harbor Freight clamps are very cheaply made, like all of their other stuff. However, as you gain woodworking experience, you will learn exactly how much clamping pressure you can put on HF clamps before they break. Also note that you dont have to really force the clamps that tight. If you really have to use a lot of strength, you are over tightening. How much is not enough and how much is too much? This is something that cant be explained in words.
