I was on a team that did Trailwalker this year. It was a great experience. One other tip to prevent blisters is to try to toughen your feet up first by rubbing them with meths or isopropyl alchohol. You can keep doing that during the event too.
With regards to clothing - layering is key. The temperatures do drop at night, but I think for the night leg I had one some thick leggings, a polyprop top with a light vest over it and a good hat. Was plenty warm enough.
Start training early and ramp it up slowly - you'll be clocking up lots of kilometres before you know it! Try to get plenty of off road training in, but training on road is fine too - especially if you can get some hill climbs in that way.
I'll try to keep an eye on this thread if more questions come up.
Good luck and have fun!!!
