I am going to do a spark plug change and wanted to know if I should also change the coil boots while I am at it? If so, what brand do you all recommend?

The plugs I am going to put in are the Champion Double Plat Spark Plugs.

Unless there is evidence that the boots are no longer insulating and are causing missing, I wouldn't change them. I say that after having two Concordes - a 2.7 that is still running great with over 270k miles on it still on original boots, and a 3.2 that I lost with a broken timing belt about 3 years ago with about 200k miles on it, still running on its original boots at the time of its demise. As they say - YMMV. Wouldn't hurt to put a skim coating of silicone grease on the boot surfaces to keep them in good shape. By skim coating, I mean no thickness - rub it all over them and then wipe off with a paper towel or rag - basically they will have a sheen that they didn't have before putting the grease on them. Put a light coating on the ID of the boot tip so it seals against the spark plug ceramic so no air gaps/arcing.

Which Champion part number are you putting in?

Actually there are replaceable boots between the each coil and the spark plug. RockAuto, drill down: DODGE 2000 INTREPID 3.2L V6 Ignition Spark Plug (Coil-On-Plug) Boot

While I've never had to replace them, there are some who have posted here that they did in fact have to replace some of theirs.
