Hi Mid-fi -
I wouldn't obsess with this on your end - any decent vinyl mastering engineer will be able to take care of any issues for you. Basically my suggestion is to make the mix sound good to you in your monitors and let the transfer engineer do what they're paid to!
As far as high end - pretty much on every transfer we'll use a low pass filter set usually around 15kHz-16kHz - but on some I've gotten as low as 13.5kHz to deal with tracks where they obviously cranked the "air" band up (which is ok with digital - if sometimes way over done on some masters - but just won't translate to vinyl). I have a feeling a lot of the warmth people attribute to vinyl is the fact that the high end is just not cranked to the point of pain as it is on a lot of CD's! But really - this is an area I don't think the mix engineer should worry about as what you think might cause a problem might translate without a hitch - and visa versa. This kind of thing really varies from track to track. When we're setting up a transfer we can monitor the current being sent to the cutting head and see when the various safety limiters start kicking - and hear based on experience when the highs might not translate - and the correct only as needed. So basically - make the mix you want - and let the mastering engineer master.
One nice thing with DMM over lacquer is that it really holds the high end a lot better - you get a lot lot less high freq loss, distortion or pre-echo - so it ends up being brighter and more defined
You can see microscopic views of the same grooves cut with a DMM lathe and a lacquer lathe & more info on the process here:

* de-ess sibilant vocal tracks so that we don't have to de-ess the track globally
* don't pan things like 2 different simultaneous bass lines left and right (although we have limiters that can sum below 300Hz to mono at a certain threshold to deal with these kinds of problems)
* avoid the urge to crank up the highs to crispy - as we'll just have to back these things right back down
* keep levels fairly even - but there's definitely no need to squash them! - we can add a little compression or limiting at the transfer if it actually needed
* keep the body of kick drums sound at a freq above 40Hz.
If you're preparing a master for a direct to vinyl master disc transfer (either lacquer or DMM) one thing is to leave around 3-6 seconds in between each cut so that there is no sound in the spiral (the wider grooves that are placed between each track - we actually have to manually hit a "marker" button on the transfer console to have the lathe cut these - so we can't place them as quickly as pq points can be!) - and it helps to have the sides seperated by at least 6 seconds so we don't have to scramble to get the fader down when the first side ends.
