3.1 has one on the fuel rail
Dealer for a stock replacement, Summit or others for an adjustable one. V-6s use the same FPR as V-8s
No clue
Same place your old one is

typically $150+

 

'Course, Summit won't verify that it'll work on the v6; their tech sheets only mention v8's, but the regulator will work. Look for one mentioning the camaro/firebird 305/350 TPI motor. Your stock fuel pressure regulator is on top of your fuel rail, underneath your "spider-like" upper-plenum on top of the engine.

Cost is about $80 from Summit. 'Fact, the BBK one is $60. Go to http://www.summitracing.com , click on "browse online catalog" (on left top), click on "air and fuel delivery" section, click on "fuel pressure regulators". Then go thru the list. Make sure to buy a fuel pressure gauge (for fuel injected engines, gauge handles the higher pressure of fuel injection) for $30 so you can tune the regulator.

But.... if you don't have serious mods (cam, headwork, headers), don't bother with an adjustable fuel pressure regulator. Work on other mods first. If your engine doesn't need the extra fuel, you won't benefit from it...
