Yes, many variables. Depends on which part of the world you want to eventually settle down in (if at all :)).

It seems you have put a lot of research and thought into things which is good. Let it settle. Although one "way" doesn't suit all, my personal recommendation based on experience is to get out there teaching for a year or two and then do qualifications. Take a simple TEFL course and then after a year teaching decide on something more substantial. You will also get so much more out of a celta/masters/certificate if you actually have experience in the classroom teaching.

Also don't forget - these are just "paper" and the real learning is how you reflect on your own teaching and undertake of your own, prof. development. There are a lot of great materials out there for prof. development ranging from social networking sites to videos to journals.
