I started with Stormlight also, and about the only problem with that is that there are a lot of references that I missed out on. So I will have to go back and re-read them, which is that so much of a problem?
Honestly though, I wish I had started with Mistborn or Elantris and saved Stormlight for last just because of all of the cameos from other books that I didn't get.
How to get back on track? Read Warbreaker. There is so much stuff from that book specifically in Oathbringer.
