Yeah - I kinda fell into IT by small degrees and mostly by accident from an accounts Monkey job.
7 years down the line I am now about to jet off to Dubai to become a "Regional IT Manager" so it does pay off......eventually!
As for qualifications.....hmm - unless you know nothing at all about computers, I perhaps wouldn't bother with MCSE's - they are ten-a-penny and IMHO pretty worthless. People fresh from school or college that I have interviewed who have had MCSE's up to the eyeballs had no fucking clue when it came to "real life" application of IT.
You will gain most of your skills and knowledge from experience and from being on "the shop floor". I have no formal training in IT and no better schooling than GCSE level - it is my 7 years experience in the industry that (finally!) gets me places.
Now - should you want to get really technical later on, then there are more specialised qualifications that will earn you big bucks - CISCO stuff springs to mind, as well as specialisation/training in specific software like SQL or Citrix etc.......these would be worth considering once you have got a year or twos experience and found your "niche"
