i'm new

[mynameisthom]

i'm new here, and i'm kind of confused about what everything means. what are the different studios (mac, ac, ex, whatever), and i don't know which of the two request forums to post my requests in. and by requesting something, does that mean it will just show up in the store, and i'll be able to get it when it shows up? thanks for any help, and sorry i'm a newb.

ps my requests are
gasaraki dvd826
gundam 0079 perfect collection ma308e
