To be honest, it's too early to say. Just focus on your job now, rather than worrying about whether you can or cannot get into b-school years from now, or whether doing a transfer will help or not.
As for GMAT scores, the five year window means that so long as you apply by R2 deadlines (Jan 2015), you'll be fine.
Again, focus on your job. There's way too much work ahead of you right now to be worrying about something like this at this point.
