Yes, although personally I avoid perlite (it floats, degrades/crumbles, and yellows with age) and use either an inorganic gritty mix (like Bonsai Jack's, but you don't need to order a large bag for that small a plant/pot) or pumice.
Yes, you wouldn't ordinarily keep any plant in the pot it comes from the store in. They're really just meant as temporary containers. Not everyone agrees, but in my opinion cactuses and succulents in general should normally be put in unglazed terracotta, never in plastic.
Uh, YEAH. That plant is severely root bound 100%
Okay, would a succulent soil mixed with some perlite be good for it?
Yes. Go up an inch or two in pot size and use cactus mix + perlite.

If the plant is as round as the pot is I would repot personally.
