Grubbyky,
There has been lots of good advice posted previously so I will try not to rehash too much.
It sounds like you may need to change employers at some point to gain experience relevant to obtaining a PE license, but your experience can be valuable nonetheless. Generally the licensing boards want to see 4 or more years of progressively responsible experience under a PE, not 1 year of experience four times, but I suppose it can feel that way.
I agree with Moltenmetal - whenver possible, for as long as possible, get out in the field, get your boots dirty, and see how things get constructed in the real world vs. what's shown on the plans.
Hang around those old-timers and pick their brains - the grizzled inspectors, superintendents, and foremen, as well as the draftsmen & technicians. You may have to take a few orders, buy coffee, or go look for a plan stretcher. Be a good sport, do it with respect and humility, and you'll earn their respect and they will readily share their knowledge. Some will share whether you want their opinion or not. You can learn something from everyone, but you will soon learn who has what's worth learning.
You'll need to demonstrate your competence, and the ability to apply what they have taught you in order to keep their respect. Stand your ground when you know you are correct, but don't embarrass them in front of others.
Also try to find an experienced PE (with real world experience as well) to act as a mentor. If there's not one at your place of employment, try the local Branch/Section of ASCE, NSPE, or other professional organization.
Communication skills will be vital as your career advances. Based on your posts, you appear to have a good grasp on written communication - spelling, punctuation, not writing in text message jargon, etc. Be consistent in that regard.
With respect to verbal communication, if your current position doesn't give you the opportunity to make presentations to small and large groups, then find another venue where you can gain that experience. Possibilities again include local professional organizations (ASCE, NSPE, etc) plus civic organizations such as Kiwanis, Rotary, Toasmasters, etc. These organizations also can help you fill voids in your experience, help the community, and gain leadership experience you wouldn't normally obtain in the first few years out of college.
Good luck!
