The more recent ones have the same HVAC filter as the T600 and T660... there's a black plastic cover on the right side of the vehicle, under the hood, and butted against the firewall. You loosen the black rubber strap underneath it, pull the bottom of the cover forward, and it'll expose the HVAC filter.. this type, if it's not damaged, can be simply rinsed out and reused.. it's a fiber mesh.
The T800 was always sort of the "Frankenstein" of KW's production line, and typically ended up being an amalgamation of components from other models... if you have an older T800, I'd need the year in order to determine which HVAC filter it used.
Need to know model year and engine in order to answer this.
The air conditioning filter on a Kenworth T800 is located in one of two places. It is either located near the unit itself, in a slide out drawer under the unit. The filter can also be at the drop down air return ducts. There should be a filter in one location only.

~4 lbs. Charge it to that point, and you should be alright.

Yes, for the W900, T800, and it is possible to get a K100 glider, although not an easy process.
