Probably one of the things to do would be to start reading through this.

It will show you the requirements, I can't see any reason why you could not start on the modules required for the licences, after all with them under your belt you would just need the experience to go with them, and having the modules done would look favourable for a future employer.
Anyone else see a problem with going down that route??
