One thing you may want to consider is summing anything below 120-200hz to mono. This was done with vinyl to keep the bass from making the needle move too far from one side to another. (No one panned bass completely to one side or another in those days...far too risky.)
Watch out for over-sibilant vocals; top end was always carefully monitored/limited to avoid smearing and a harsh top end. (Remember; vinyl would simply bottom-out when pushed too hard. There is distortion, but not like digital clipping of today.)
Overall, a good multiband limiter (with "Look-ahead" capability) used sparingly will help too (with the bands UN-linked, so they operate independently.)
If you're going through a DAW for your final mix (before pressing into vinyl), you may want to carefully trim/tame any rogue transient peaks. They didn't have this luxury "back in the day", but they handled it well with the excellent limiters of the era, including optical circuitry. (Real-time Look-ahead limiting was used, too, with a special playback head put in the tape path ahead of the actual playback head. This gave the limiting circuitry a bit of lead-time to anticipate the incoming peaks.)
Also - and this is rarely mentioned - but the best songs were put at the start of the LP for more than the obvious reason (best foot forward). It also sounds the best here....vs. the inside of groove, near the label. Due to the speed of the rotation at the outside of the LP (much faster) than the inside (much slower), and other factors, the frequency response & SN ratio was the best on the outer grooves. (Actually, the really "Sweet" spot is further in, but that's another issue for another discussion). Most importantly, the difference in EQ between the beginning of an LP's side is 5db down at 15k by the time it's at the inside grooves. Since it's gradual, no one notices this over the 20 minutes or so of an average LP. But it's there, and easily detectable if you were to pick up the tone arm from the beginning and move it to the end of the side. Of course, you don't get to compare the same track in an A/B situation, so again, it's rarely noticed by all but the most golden-eared.
Izotope used to make a plug in (probably still available?) that will do all kinds of terrible & fun things to your sound to emulate the ravages of mistreated vinyl, including ticks, pops & surface noise. That might be a good final touch for you.
I could go on about the, ahem, "merits" of vinyl, but I wouldn't want to incurr the wrath of all the newly-born vinyl enthusiasts out there. ;-)
Personally, I'd get the most out of your analog adventure, and just make a nice CD or 256bKps MP3 out of it.
