As for the cooling issue, my first guess is that your system has a low charge and possibly a leak.
No, the water rushes/sloshes just at startup, not all the time. Where can I get a kit, and is it something that a mechanically incline individual can tackle, or are there special tools required that I should take it to a shop for? Where is the drain tube and how do I check for blockage / correct the blockage if it exists? I have checked my Haynes manual and have not found an A/C drain tube.

I keep up on my fluids pretty regular, but I haven't checked the coolant in about two weeks, and this sound has been going on since before then. If it is a heater core leak, how would I know? Replacing this would require discharging the lines right, therefore I would probably need to take it to a service center to have the work done? There are a few things I really try to steer away from; some electrical, gas lines, A/C components.
