Wow.. congrats on one of each! So they're both boys? I'd definitely crate separately. Colleen's set up is ideal.
I'd start brushing and trimming their faces the instant you have them. Even if you don't really shave any part of them, pretend to. One thing about some cresties is they have a fear of the trimmers near their faces. If you start early enough, you may just win that battle.
I have a true hl girly and a VERY hairy hl boy. I hate hate hate shaving him. Tiny little bony elbows are such a pain. And his hair is kind of thick so I get hair splinters from him all the time. blech.
I have 2 poodles and a bichon also, so I'm doing a lot of grooming on a regular basis. I'd go true hl in the future
