As the man says, you need to time it so your not entering the job market until at least 2 years from now. Enjoy your flying, build some hrs, do a night rating, take some friends places and get regular check rides with an instructor to make sure your keeping on track with the CPL in mind. Could also look for para dropping or glider towing for some cheap/free flying.
Consider an IMC rating, it will help with the IR when it comes but isn't essential. Get the ATPL distance learning material and study at your own pace, but I'd leave it at least a year before you sit any exams or do the residential bits.
Also, get RANT and learn NDB holds and entries. Much easier to do this if you have done the IMC course.
