stock brake fluid?
I need to refill my brake fluid for the time being but I'm a newbie at this so excuse me for my dumb questions... first what kind of fluid can I use to mix with the one already in a wrx? and finally do I just poor it in the brake resevoir or do i need to take some precautionary when adding brake fluid?
also where can I get a good aftermarket radiator?

check the manual, it should tell you what kind of brake fluid came in the car stock. a far as adding fluid goes, you can pour it right in. *however* i'd be curious as to why you are low. if you have fluid leaking, that means that there is probably air in the system, and you'll need to bleed the brakes. oh yeah, don't spill the brake fluid or get it on your skin, that stuff is evil. see now, this is a pefect time to upgrade to stainless steel lines, and bleed the brakes with high quality Motul fluid...
speedmonkee makes high capacity (i think?) radiators, you might check with them.

try dot 5, silicone. it won't eat up the paint if it is spilled. it has a very high boiling temp. it doesn't absorb water. one downside, it won't mix with dot 3 or 4. you must rebuilt the master and all 4 slave cylinders and completely flush out the lines. there can't be any other brake fluid in the entire system. the other downside is the price and availability. very few people use it so it almost has to be ordered. it is about $25 a quart.

Not only NO, but HEELLLL NO(!!!) on DOT 5 in our cars. This is a LIFE THREATENING (as in, your life) mistake in our cars!!!
Use a good DOT4 fluid. For a "street" car, I'd got with the Valvoline DOT4 (about $5/bottle, and commonly available at Autozone or Pep Boys) or ATE (Superblue or Typ2000). All are readily available, better fluid than stock, and reasonably priced.

SRF is good stuff and will give a little more boiling resistance. Downsides being it is REAL expensive (!) and won't last long.
Personally, I'd try different pads first. I think you may be overbraking your pads and causing them to run too hot. What pads are you running now?

DOT 5 is usually used in show cars so that it won't damage the bling-bling paintjobs.

Who says your brakes will fail using dot 5? My father has used dot 5 in an 83 Toyota Celica and a 86 Toyota 4Runner, both of which said to use dot 3. He has NEVER had a problem with his brakes. He has 150K miles on the 83 and 220K on the 86. I would say whoever told you that is full of crap. In fact, I know they are. I am planning on switching over myself.

for pads i am using ceramic pads that come with the rotora big brake kit
i had on there axxis ultimates before.. with motul..
i don't actually brake that much, because for some strange reason, i dont trust my brakes, so i try to brake as little as possible. just a tap at the very end...
so i dunno
do i need to flush everything out before adding castrol?
