1995 Honda Accord Honda Overheats again what 2 do guys?

O.K. I was given the best car on Earth on my 17th birthday and have had a few overheating problems with the car. First off, I recently removed the head and had it re-surfaced and pressure tested because of a blown head gasket that I found out was due to an exhaust manifole with 3 loose bolts, whoa, then ok in July of 2006 it overheated and caused the radiator to crack in front near radiator cap so I replaced it at Gordon's radiator in Winston Salem, NC they did an excellent job but even when I replace head, all new gaskets, and water pump, I was on my way back to Greensboro from Winston about a 30-40 minute drive it was overheating. But dang I jus did huge overhaul less than a month ago. How am I loosing antifreeze? Could it be a loose radiator cap it felt tight but not too tight? I replaced timing belt, and water pump, new gaskets, new water pump, new spark plugs and wires, new oil change, and fresh antifreeze, how did my hose connected to engine under distributor get small tear in it well I know it was overheating for maybe 10 minutes or less but as I put in new antifreeze it leaked right back out once I got back to campus and when I put maybe 1/4 of a full bottle of 50/50 it idled up and down really hard could that be the idle control valve going bad or just because it didn't have enough antifreeze and I had small tear in antifreeze hose going to engine. Well it's parked and I have the money to get the hose fixed but don't want to deal with any more overheating problems what should I do with my beloved accord and where should I go to get it fixed and what should I fix?
