If you are planning to go to Thailand to train, it would be a good idea to train Muay Thai so you can build a basic foundation. If you plan on having a fight while you are there, start training now. Also you might start to train in Muay Thai and find out that you don't enjoy it very much. It would be better to find that out before you leave. With that said, try BJJ as you may find the ground aspect is more suited to you.
That's the right advice. Thailand is a long way away and you don't want to go all the way there to do something you dislike--and most people dislike getting kicked in their thigh, so it wouldn't be remarkable if you did too.
I'd also make sure you're in as good a cardiovascular condition as possible. Being a small guy sounds better than being a big guy in this case but make sure it's a solid 140 you're bringing over. Again, it's a long way away and if you spend half your time slouched against the wall trying to catch your breath it's going to be a waste of time and you're going to lose the respect of the peole you are training with. Make sure you're in your best shape so that the Muay Thai training is really learning Muay Thai--not doing a weight loss and cardio program.
