Either A.M./P.M. or a.m./p.m. is considered correct grammatical style so long as the periods are in place (since A.M. and P.M. are both initialisms).
No, just put periods after both letters- "a.m. p.m."
It is not necessary to capitalize a.m. or p.m.
Examples:
We'll meet at 8 a.m.
Have dinner ready by 7 p.m.
AM PM are supposed to pe capitalized in general so yes

If you mean to write it out in letters and words then it's Four thirty pm.(Note that according to some styles, only numbers are used with AM and PM.)
