I agree on Campelltown, It's a cool kit of a ship that was really built in quantity but hardly modeled. Be aware that the kit is in no way similar to the ship at the raid, but is a reasonable USN four piper and looks the part. The wood decks are wrong but i would just paint them gray.
Whether or not you use PE is a matter of taste, the model will be satisfactory without it.
Upgrading the guns would be a fun thing to do. They do look silly, but are big enough that it's not too fiddly a project. I looked around for replacements, but the model is a weird scale so there aren't any. I did that to the Emden, which is a "normal" scale and it really helped the model a lot.
I have not built either of the Lindberg models, but their reputation is not a good one, so I would hold off on those. I would build that sub too, and wait on the BB until you have a feel for the skills invovled.
The Emden is unfortunately out of production and can be pricey. You just have to watch eBay and pick your spot.
