Redline MTF (manual transmision fluid) or Honda MTF, if your going to use Mobil1, use the MTF. If the synchros grind, use Penzzoil Synchromesh. There are other synchromeshes out there, but that one was the easiest to get my hands on and they are all about the same.
As for changing it, there is a drain plug on the bottom of the tranny. Loosen this and drain the fluid. Put bottom drain plug back in the case. Around the area of the axle on the passenger side of the tranny there will be another bolt, much like the bottom drain plug. Take this out and pump the fluid in until it starts to run out the refill plug. Put plug back in to the hole. Now you done..... this should take like <20 minutes.

i can't figure out which is the drainplug, there is a bolt that takes a socket wrench with no socket(you just stick the wrench in) but it is very tight. i am not even sure if that is it. how would i loosen this bolt? also is the fill on top of the tranny on the pass side or just above the drain plug? i attached some pics...the first is pass side, 2nd is drivers side, 3rd is what i think is the filler.

the first pic is the drain bolt, but the 3rd is NOT the filler hole, i have been looking around to see if it is possible to put the fluid in there though, since it is a breather, but no info found yet. the real filler bolt is same location as the drain bolt, but higher on the tranny, i dont have any pics to show you, but you should be able to recognize it

if you dont want to break the filler bolt (which is the other bolt in the first pic. the one right next to where the axle enters the transmission) use pb blaster or wd-40. they will do about the same thing. you can use a flexable funnel or if you have the cone plastic tip on the bottle of fluid you can put a rubber hose and squeeze the bottle. thats what i did.
