Re: aikido bokken / kenjutsu
Iaido - kenjutsu: Actually, Muso Jikiden Eishin Ryu, Muso Shinden Ryu and a couple of other iai styles I'm familiar with DO have a kenjutsu component. In MJER and MSR, the Tachi Uchi no Kurai is taught fairly early on, and there are otehr sets of paired kata later.
Kendo is a cousin to kenjutsu, but has a different approach and methodology.
There is decent kenjutsu to be found in the USA ... but you have to know what you're looking for, know what kenjutsu isn't, and be prepared to do your research.
Right there in your neck of the woods, sort of, you can find the Kashima Shinryu folks at U. of Ga. at Athens. I don't know if they're accepting students who aren't uni-connected or not, but Karl Friday's one of the best and most knowledgeable teachers you'll find in the US.
As noted before, koryu.com, the iaido-l mailing list and e-budo.com (if it ever comes back online) are excellent resources.
Get your hands on the Koryu Books trilogy (see koryu.com for details), anything written by Karl Friday, Dave Lowry's stuff is pretty good, too.
