To the threadstarter:
You have to be more specific. What are you interested in? Why do you want to learn, etc. Self defense? Fitness? Bar brawls? MMA competition? Standup competition?
All TMAs have useful things to offer, but depending on your goals, they may be more or less suitable.
TKD is great for kicks and footwork, especially if you have good hands from boxing already.
Hapkido depends on the instructor, it covers basically every aspect of fighting, but the focus and quality of instruction can vary. Expect lots of standing joint locks, and kicks/punches/strikes similar to Karate styles.
Karate has many styles, the full-contact ones tend to be more popular with the kickboxing/MMA crowd for obvious reasons.
I agree with Gregster, you should have a look at the gyms and see which one you can imagine training in. Maybe they are all crap, who knows. Maybe there are some really good ones.
BJJ+wrestling+boxing is a good base, so you don't HAVE TO do anything else. If you would like to learn some kicks, then go back to the beginnning and ask yourself about your goals.
