Jim,
This question concerning a choice for first Kit has been asked here numerous times, and my recommendation is always the same, the Wingnut Wings Sopwith Pup. (if you can get it......) It's a very nice build, the rigging is relatively straight forward, and there's numerous great schemes for both versions. With your stated preference for British subjects, what's not to like about a Pup!!
As for jigs I use both the AeroClub and the Vertigo version as recommended by Gaz, and I am a true fan of the concept of using jigs for assembly.
Cheers,
Lance
