The rims are Mavic XC 117. Its a 26" wheel. not sure if its a 559-17. They are the original wheels from a Felt Virtue 3. So you think I should keep these wheels for street use and have a wider set built for my single tracking?
Your MAVIC XC 117 are 559-17 (the last two digits in MAVIC's designation is often the bead-to-bead width ... if you look at the label near the word 'MAVIC' you'll probably see the numbers 559-17 which is the rim size).
I don't know how much wider the rims have to be be a noticeable-or-real improvement over tubeless 559-17 rims & tubeless tires ...
Supposedly, the cross section of the same tire on a wider rim allows for a better contact patch at a comparably low PSI ...
So, in theory, a 559-19 tubeless rim & tire will be better than a 559-17 tubeless rim & the same tire, but a 559-17 tubeless rim with a tubeless tire may be better than a 559-19 with a the same tire + tube ...
I guess that the advantage really depends on how low a pressure you like to run your tires ...
Although the theory of a wider rim makes sense to me, I don't have any tubeless setups ...
You need to try to get "a second opinion" on rim width & tire pressure, etc. before you buy the second wheelset.

I guess I'm at the point where I don't care about my speed and just want the exercise with greater comfort. And I'm tired of taking care of 2 bikes so I was thinking of simplifying. The suspension bits lock out at both ends for road work so I thought I could give the road tires a try without loosing too much speed.
Okay, that makes sense ... but, try a few rides on your MTB before you abandon your road bike.

I'll try the city slicks tires you mention, but the current rims are a tubeless setup. Do I still need the tubes for the road slicks?
Yes, you will need tubes for the 'slicks' because the tires, themselves, are not designed to be tubeless.
