I'm interested in this too. I'm working on two CDs at the moment, and they're going in opposite directions on this front
Normally, I start with the simplest song (track-wise - so the fewest overdubs, no extra percussion etc.), and once that's done I transfer those settings/plug-ins to the other songs and tweak as needs be. I've got one session going exactly like that at the moment and it's all lovely and working fine - takes a couple of hours to set up the track, edit stuff, remix to fit, automate bits etc.
However, I'm also doing a CD where the recording has been all over the place - the drums and bass were done in one go, but guitar-wise 2 songs have mic'd cabs, one has mics and amp sim/impulse, and one only has amp line-out/impulse. Some of the vocals were done on a dynamic mic, some were done on a nice condenser... we got caught out because one of the tracks was going on a compilation and had to be finished early, which meant we couldn't record everything at once (we had to get everything down for that one song). It's a mess basically, and means I can't just use the same settings for everything. Trying to get the songs to work together in context is proving a proper nightmare - I can't even keep the drums sounding the same as they just don't translate with the different guitar sounds. I don't intend to work like this again
