No. You can become an AFOSI Special Agent without being given a polygraph. The polygraph for hiring purposes is reserved for positions that can be applied for for once you become an agent. The polygraph is not required to obtain a TS/SCI. I'm sure the government would like to mandate this, but because of limited resources/manning there would be a huge back log.
Yes, AFOSI SAs are federal agents (1811). Check the AFOSI page for more information. Top notch organization, although extremely difficult to even be granted an interview - they select 20 interview candidates out of several hundred applicants, and then only submit 10 of them for consideration for training.

The FBI's job is to enforce federal laws. Federal laws are created by the president, in this case, president Barrack Obama. They won't pull people over for speeding, or respond to normal cases, because those are state laws. An example would be marijuana, it was made illegal by president Nixon, it was, and still is a federal crime to have, or smoke it.
