At 111k I would replace the plugs and see if that fixes the miss since it is due anyway. I recommend replacing the coil boots when replacing the plugs. The most consistently good results have been with motorcraft plugs. Some people have good reviews of the Champions while some report nothing but problems. Personally I put motorcraft plugs in and got the cheap duralast boots from autozone for my truck. Be sure to read up on the plug change for a 5.4 3 valve if you haven't already. There are some good tips out there but be prepared for at least one to break.

More than likely your blinker problem is the multi-function switch. While I don't know anything about the accel plugs I would still recommend the motorcrafts. I have always had the best luck with Motorcraft in Ford and Delco in GM vehicles when it comes to spark plugs. I would only replace the coils as needed personally. If you are hoping to see a power increase from a "hotter" coil I think you will be very disappointed.

Stick with the motorcraft plugs, however, I had to replace a coil so I went ahead replaced them all with ACCEL Super Coils 140033-8 - SummitRacing.com and I have been pleased with the product. Your not going to see any significant gains, but it is a quality product and is cheaper than a motorcraft set of coils.
