I wouldn't even worry about the p/s fluid just buy some Honda p/s fluid and top it off if need be. The transmission fluid is as easy as draining and refilling it. Just buy 2 quarts and some drain plug washers from the dealer and you should be set. The transmission has a drain plug and a fill plug, the fill plug is above the drain plug obviously. When you fill the tranny just fill until the fluid starts to dribble out of the fill hole and when it stops then it's topped off and screw the fill plug back on.
