After Telluride, I would head back to the Ark Valley for a bit if you do not hit up FiBark on the way or head back again anyway. Tons of camping, good water, and a good chance of hooking up with people to paddle with.
Then I would consider driving over to Vail valley for some boating on the Eagle, not as good camping as the Ark but can find some nice places outside of the towns on the I-70 corridor. Next, head west to Glenwood Springs and boat the Colorado/Roaring Fork/Crystal.
Maybe hit the Poudre after that in Fort Collins, leaving Denver/Front Range stuff to hit on your way back down to the Lonestar state.
One nice thing about not having a set schedule is you can go where the water is best. Its been a weird spring with cooler weather and lots of rain so like advised above come up with some runs on your must do list, check the gauges, and then make a plan.
Runs I would put on my list (flow dependent) to check out in the guidebooks:
-Ark: Granite through the Numbers, Clear Creek of Ark, Royal Gorge
-Eagle: Dowd Chute through Avon/Edwards, Gilman, Gore
-Glenwood Area: Slaughterhouse, Bogan, Narrows, Glenwood wave if you playboat
-Poudre: Middle Narrows (Lower Narrows being worth a scout) on down
-Front Range/Denver: Multiple sections of Clear Creek, Bailey, Foxton/Waterton
I think I need to take a sabatical now - stupid work.
