Reddit mentions of CycleOps Training Mat - 36in x 65in

Yes your trainer choice sounds spot on.

1. maybe, but i would recommend a trainer mat. it is a few mm thick rubber mat that will absorb most vibration and keep your sweat puddles contained.
   
   
2. No, you don't need a special indoor trainer tire. any slick tire will work. Personally, i have a trainer tire that i throw on my bike for the winter months because i would prefer not to put wear on my nicer road tires.
   
   
3. There are a number of throughaxle adapters out there for trainer usage and yes you would need one. Though there are a few different types of threads on through axles. make sure to get the right adapter. If you pull the through axle out you should be able to tell what type of adapter you need based on the type of threads that you have.
   
   
4. No. It will not damage your bike.
   
   
5. It does but some wear on components, but if you completely clean and lube your drive train before putting in trainer miles, the wear is pretty negligible because your bike should stay quite clean.
   
   
   
   as other people have said, Zwift is totally worth the $10 a month(you can run it on your phone or a tablet if you want to focus on the TV... personally, zwift keeps me engaged enough that i don't need the TV.), if the trainer doesn't come with a climbing block they can make a substantial improvement on the comfort of riding a trainer.
