If it was leaking then it would have been obvious when you removed the transmission; the area inside the bell housing would have been coated with the stuff. I was thinking more in terms of preventive maintenance since it was easy to access with the trans off. So your oil leak is likely the valve cover gaskets, the easiest of them all to do. If you can't do it yet, at least change the PCV valve (on the passenger side valve cover IIRC) and see if that helps; the PCV valve helps maintain some sort of vacuum inside the crankcase in order to prevent pressure buildup and reduces winding losses of the reciprocating crankshaft and bottom end assembly.
I understand the financial situation you speak of. Are you handy with tools? If so you can do the valve cover gaskets yourself with basic hand tools.

handy with tools, i am. having a place to work, i do not. live on a busy street, park in the street, and the po-po, ya know. i actually did check the pcv valve, pulled it off, checked it, it was clean and works properly, so, something good for me to know, knowing the pcv valve is working, and that undue pressure isn't building inside the crankcase to force oil out through seals and elsewhere one doesn't want oil to go... i've looked, and don't see any oil tracks down from the valve cover gaskets, really. i'm just keeping an eye, occasionally driving up on a curb, or jacking the car and climbing underneath with a light, if i'm lucky enough to have found parking on a side street. difficult, since apartment buildings. all the overflow parking is what it is, on the street, and daily everyone fighting for a spot closest to where they live. heh. the other night, i came home midnight, had to park half a city block away from home. got lucky today, right by my front door. life in the city..

At this point, considering everything else you've said, it seems like your minor oil seepage isn't serious enough to be a concern; if your oil level stays good and it's not dripping out then maybe try a high mileage oil next time the oil change is due.
And I remember fighting for parking back in my So. Cal days... not fun.. but the sunshine was nice.
