Re. Class 1:
You should a) read through the exclusions list and check you don't feature on any of the exclusions b) go and get your initial Class 1 with all the harrowing ECGs etc.
If you can't get a Class 1 you cannot go commercial so it is the thing you do
first before you even beginning to think about a career!
There are 3 places you can get an initial now:
