I'll second what a lot of people have said so far... don't get caught up in the BS too much. Figure out a study plan that helps you learn the law, not just memorize the facts. Learn early one what is 'material' in a case and don't worry about the other stuff. It will help yoube able to brief your cases more quickly. I don't think its wise as a 1L not to brief cases, but I also don't think you need to have long drawn out briefs. Lots of times I just write a paragraph or 2 in my own words of what happened in the case (rather than parsing out who the parties are, the facts, the hodling, etc in separate headings). The point of a brief is to be able to pull out the RELAVANT information to spit out to th professor to show you understand the case. For me, that means sometimes I can do that writng a paragraph full of fragmented and run on sentences.
Also, supplements....especially the E&E series, I can't stress their value enough. Those things are my bibles and because of them, I understand the material. I read the case book and half the time it doesn't make any damn sense, no matter how many times I read it, but if I have read the E&E on that topic beforehand, I can breaze through the cases because I know what the concepts are they are talking about. I have a bunch of classmates who insist they don't have the time to read the supplements, but seriously, it is way worth it. If reading them (which doesn't take nearly the time reading the case book does) helps you understand the material so that you only have to read the casebook once, rather than 4 times, then it's worth it.
My Crim Law one and my Property one are my bibles becasue those professors tend to each much more esoteric theory rather than BLL in class, so the supps give me the BLL.
Oh, and if you have been a paralegal since God was a kid, please please please do not think that makes you smarter than the professor and try to prove them wrong EVERY DAY. And please, if you MUST raise your hand, please do not preface every statement with the words "At the law firm I work at we had this case where...". Trust me, no matter how much paralegal experience you have, I guarantee you the Professor knows more than you do. Guranfuckingtee it. Please...just don't be that guy...
Ok, mini rant over..
