Ali,
I'm 36 and I'm going for it. If you can get the training done in 18mths-2yrs you could still make Captain by 45.
All the info you need is probably on this site somewhere (if often contradicted). Have a good look through Wannabes.
Get a Class One Medical, do a JAA-PPL in the USA and reach for the skies!
PS You could do the ATPL groundschool after getting your CPL/IR if you want. That way you could maybe work as an FI or glider tugging etc - if you can find a job. (Crap money though).
