Which one is more effective: MCSE OR CCNA?

I am looking for a career change and am very interested in computer networking (having designed, installed and configured a few for myself, friends etc). I have no actual employment based experience or qualifications in IT (apart from a Dip He in Multimedia) and am therefore considering studying for a MCSE or CCNA exam.

I have a few questions with regards to this:
1) I have several possible avenues of study open to me – namely:
Distance learning
Boot camp
Self study

Which is considered the most effective?

2) I want the opportunity to work in Europe and to select contract work when possible (to maximise my free time). Is there any difference between the two qualifications with regards to their acceptability in Europe?

3) Which is considered the most popular when it comes to employment opportunities?

4) What are the chances of getting a position with a company, and getting them to train me for these qualifications?

Any advice offered would be greatly appreciated.
