I'd double check the bolt pattern on that 1.5L before ordering anything since the 3-cylinder setup might be different from what works on the 2.0L engines.
I'd probably go with the 1.5" lift like the other guys said - seems like the 2.5" is more hassle than it's worth if shops don't want to touch it and you can't run bigger tires anyway.
Sounds like it could be a CV joint starting to go bad - pretty common on vehicles with that kind of mileage, especially if you do a lot of tight turns or parking lot maneuvers.
Yeah I'd definitely go with the $20 Ford TPMS tool route like rorlow mentioned - way cheaper than paying the dealer to do it every time you swap wheels.
The 17x7.5 +30 with 235/65R17 should be pretty safe and won't rub, might look a bit conservative but better than dealing with rubbing issues every time you hit a bump.
Yeah Ksnau is right about the bypass being integrated into the compressor housing on these newer ecoboosts, but I'm not sure if that spacer will work on the 1.5L since it's a different setup than the 2.0L.
