If you want to apply this fall, I'd set up your lsdas account soon, so you can start getting recommendations and transcripts together. I know a couple of people who got recs in very late, and it really really hurt their applications. Even if you don't plan on applying until later in the admissions cycle, it will alleviate an unspeakable amount of stress knowing that all your required pieces of info are where they need to be ready to get sent out to schools.
As for books, you listed the ones that people on this site seem to recommend the most. You'll definitely want to pick up as many real tests as possible, like 10 Actual LSATs, 10 More Actual LSATs, and perhaps most important, the Next 10 Actual. It would probably also be helpful to drop the $8 and buy this past June's lsat just so you have the most recent example of what they can throw at you (and it was kind of a female dog, if you haven't read any of the posts about it made by many of us who took it. There were some unexpected, if relatively minor, changes in terms of section difficulty and length. (a harder 28 question RC, an easy 22 question LG section)
