Hi billyshears. Welcome to the forums.
There are some pretty strong views on frameworks around here—on both sides of the fence! Personally, I don't like them, as they are full of bloat, and often end up making life more difficult, as you have to hack them around to suit your need—rather than starting from a lean, clean slate.
Having said that, there is no doubt a lot you can learn from them, too, so by all means dig into them to see how they are built. That will certainly give you a lot of ideas on how things can be done. Foundation and Twitter Bootstrap are pretty big at the moment. For HTML5, the HTML5 Boilerplate is also good to look into for ideas about how to do things.
