How much fluid?
 

Should I order if I want to do a brake fluid flush and refill it? This is on a 2000 RS if it matters.

get 1 big thing or 2-3 small containers

I use 1L for my WRX, should be enough but it wouldnt hurt to pick up 1.5 or 2L just to have backup for now and later...

to flush and refill you should probably pick up at least like 2-3L to be safe...

it is different for sti owners because your calipers have more capacity, but i doubt that much fluid is actually necessary

that was from reference from my mx6... it took alot of fluid to flush it.

On another note, if I upgrade calipers, I should be able to just take off the pads and swap em over right? (if the calipers take the pads of course)

And I got 2 L for future needs just in case (should last me enough)
