Yes, a track saw is a good way to get a nice surface for glue-up. I do not hand plane after doing this and get results that are plenty good enough for me. If my hand plane skills and hand plane bench were better I might plane the surface. But unless you are really good with a handplane (and I am not) you are as likely to make it worse as you are to make it better. I don't like the surface from my Freud ripping blade, however, as well as the 48 tooth blade my saw came with. I think the higher count blade will make this cut. I've trimmed a softwood exterior door with mine and it didn't seem to be straining.
