1 looks like aluminum caps will be fine. Tantalum is a very precise cap and tended to be more expensive. But we shouldn't worry about minor value varation with fans.
2 Go with 1k
3 I'm not sure I understand 12/rheo and 12/rheo/5 but if you wanted one that is 12v to ground and another 12v to 5v (7v total) then just built the circuit the same. The voltage input would just be different.

i want to be able to choose between:
12 - full speed
reho - 6.5 - 10.5 (or what ever the LM317T gives me)
5 - silent mode
by using a switch
