Without a doubt, go for it.
When i started my instructor course i was technically less experienced than yourself, having only completed the CPL (and 220 hrs total time), without the MEP or IR. having since completed all those courses i can say that the course i learnt the greatest deal from, and enjoyed the most was the FIC. A year on and im still enjoying the job, as stated above, you will have to put the plans for financing the DB9 on hold, but on the good weather days at least, you will struggle to find a more satisfying job in the early stages of your aviation career.
Hope this helps
