If it were me... Spokane to Sandpoint would be SR 290 (WA) Idaho 53, 41, 54, 95. Actually beeter would be Centennial Trail to Post falls then north to 53. Just last weekend I rode the centennial trail from Spokane Valley to Post Falls and back.

In Washington it iron Horse State park west to the Columbia then it is the john Wayne Trail. The map shows spur lines to Spokane and Cd'A Id. however I'm faily certain that the rails to trails Fish Lake trail out of Spokane does not exactly connect. Something to research further.
