Help with rear calipers and lines

[astrocowboy5 at hotmail.com (Jonathan Mohan)]

i got new rear calipers, ss lines, and a pressure bleeder and i have a few
questions.

can i just bleed the old fluid out with air after i flush it with some cheap
dod 4 fluid (i have ate blue for after the install)?

do i need to replace any hardware with the calipers or can i use the old
with some loc tite?

is 2l of ate blue enought to re fill the brake system?

my brakes squeek will putting anti-seze on th eback help?

are ther any tricks i should know of before i take on this project?

thanks
Jonathan
