If you're really having a difficult time, you may want to see if you can put law review off until 2L, when most law students do it.
You seem like you're extremely organized. There's not too much else to do, except make sure that when you are studying, that you're focused. If you still feel like you're not where you should be, talk to someone. Law review and journals, from what I've heard, are a hell of a lot of work. Everyone I've talked to with LR/journal experience say that it looks great on a resume and helps your career out a lot, but you definitely put the work into it. I can't imagine trying to get cite checks done while trying to make sure my 1L grade didn't slip. If it comes down to having significantly lower grades than fall semester and 1 "extra" semester of law review (assuming that they'll just reserve your spot for next fall), I think I'd prefer to keep my grades high and take the normal route of working on a journal my second year.
And if you're worried about your resume, if they'll hold your space, you can put that you've been invited onto law review for Fall 2006.
