See if you can download a setup manual for the venerable fruitbox Linn LP12. If you treat the TD150 in a broadly similar way regarding arm-cable dressing and clamping to the new plinth and obviously the suspension and bearing fettling too (EP80 makes an excellent replacement oil for these bearings IMO)..
A decent mat would be to advantage. I respect the old Td124 multi-ribbed mat, but the later 150/160/125 mat isn't too hot in terms of record support. My advice is to avoid felt mats, as I think summat a bit more substantial suits the deck's sonics better - IMO...
Plinths? An old LP12 plinth is ideal and the 150 chassis drops straight in (). The fixings are slightly different and there will be a gap alongside the armboard, but it works a treat.. Russ Collinson does some nice new ones I believe too.
Good luck - and piccies please once you get going.
