I like 1007, and use it quite a bit. She's a fermenting beasty (be ready with a blowoff tube), yet leaves a good malty background.
But, holy moly, that OG is arghh! Seriously? 1.102?
My highest OG so far has been around 1.090. I don't use any containers bigger than qt. size for starters, so what I would do is make a regular starter, then when it's finished, split it to two containers and do another stepped-up starter, and maybe even consider a third step-up. And yes, pitch within 36 hours to have an 'active starter'.
But really what I would do, is brew a smaller batch (1.040-1.060) first, then use the slurry from that one to pitch the monster. An altbier would make a good 'first beer'.
EDIT- oops. Didn't see the WLP. I imagine WLP1007, is not the same as WY1007. So, I have no experience with WLP1007. Still, enough of the remainder of the post is relevant, so I'm not going to delete it.
