Prep for new emunand

I've been running pastacfw 9.5 firmlaunch on 9.2j since I first got my n3ds, and it's been working out for me with firm spoofed games and such, so I never really bothered to install emunand cause the farthest you could go was 9.5 anyways. Now that Reinand seems to be pretty stable on 10.5, I think I'm finally ready to make the switch and I've got a couple of things I'd like to confirm before I take the plunge.

I have a lot of cias installed and I have only about 4gb left on my 32gb...
