This is sort of gilding the lily but for my $.02 I'll add these:
If it's at all possible, get a shop vac hose close to the slot to pick up the chips as they are cut. This will help cool the cutter, too !
Also, I seem to recall that Machinery's Handbook (somewhere) recommends slower speeds for slotting than for edge milling. That seems reasonable since both sides of the slot are being cut simultaneously and more heat will be generated (the chip re-cutting adds to that load, of course).
