Before you start the brake job, remove excess fluid with a turkey baster....
I'd be much more comfortable knowing that my fluid was up to the max line, and owuld probably freak out if the brake fluid level light ever came on while driving. That's just me, though.

Rather than suck some fluid out of the master cylinder and then pushing the fluid back into the master when the pistons are compressed, I prefer to open the bleed port on the caliper when compressing the pistons. This way you do not force fluid backward in the system. Ocassionally, especially if the fluid is old, or if you push the piston back too quickly, forcing the fluid backwards will cause a cup in the master cylinder to collapse making it necessary to replace it. It is not a big thing, but sometimes even the little things make a difference.
