I put near 15k miles on a paired spoke 2008 Race wheelset. Other than being a heavy, low-end wheelset, they performed fine and held up well. Never needed truing. No sign of stress at spoke holes. Brake tracks showed no noticeable wear, appearing flat from edge to edge. The wheels still spun and looked near new when I sold the bike.
I'm sure I could've put many more miles on them. Other than keeping the pads and brake tracks clean, I didn't baby them, since I really didn't care if I had to replace them. Dry weather, 160lbs, mostly flat and low gradient miles, KS salmon pads.
Your wheels have cartridge bearings. Nothing to maintain. Just ride them until the bearings wear out then replace with new. I believe the hubs are rebranded Formulas: nothing special and not worth relacing. Ride the wheels until your brake tracks are too thin or until you see a stress crack at a spoke hole...then dispose.
