So my question is, if I started with one edge out of the jointer (I pay the lumber yard to joint one edge), and am really careful ripping the other edge on the table saw with a quality rip blade, could I effectively joint that edge by going over it with my smoothing plane? The deviations from true should be small since I m coming from a relatively good rip and I m not sure the length of a jointer plane would be necessary. Am I thinking about this wrong?

Yes, you can in that situation, I’ve done it many times. If you get a good, straight rip off the table saw, a couple light passes with a smoothing plane to clean up the saw marks will not cause the edge to go out enough that it can’t be clamped up well. Do what OSU says about jointing both edges to be glued at the same time. Lay out the pieces like you will glue them up, fold the two top faces together and then joint both of the edges to be glued at once. Works slick once you get the hang of it.

If you are going to continue down the hand plane path, a jointer plane would pay for itself quickly by not having to pay the lumberyard to joint for you. A lot of people use a #7 or #8 size for jointing. I use a #6. It’s long enough to get a good straight edge, works nicer for flattening panels and you can generally find #6 size planes for about half the cost of a #7 due to lower demand. A transitional, like SMP mentions, will also work just fine if you can find one where the wood body is still in good condition.
