re: bring ya a-game and sh*t
Please note that we try to avoid writing swear words (cuss words) in full on the forum. Some people find them offensive and we also have minors using the site. As you can see, I have changed the word to "sh*t". I have edited both the title and content of your original post to remove the word too.

Oh, you know, just my clothes and sh*t.
What did you buy at the supermarket?
The usual stuff - vegetables and sh*t.
In the context you gave, it means that the people who are coming (to somewhere unspecified) need to turn up with their best abilities and other unspecified assets.
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
