This is just my personal advice, and caveat, I haven't been selected yet so take my advice with a grain of salt.
It sounds like you have some stuff you need to get straight on your end first so if I were you this is how I would prioritize my time: the first thing you need to do is get yourself straight with height/weight and PT. As a Leader in the Army, physical fitness is important and the Soldiers around you will expect you to lead by example. This is why PT is an important factor for the board. It's free chicken; get yourself on a workout plan, exercise on your own time, quit drinking for a bit and eat right. For the SIFT, buy a good study guide, print off the FAA rotorcraft manual, and study study study. I took 3 months and prioritized my personal time for studying for the SIFT. Take as much time as you need but study your ass off. When you are IAW AR 600-9 go schedule your flight physical and get it done. Remember if you don't have a 40 or above SIFT and an approved 1W flight physical you aren't even a candidate. Focus on these 50 meter targets. In the meantime volunteer for everything you can at your unit. Every range coverage, every school, every board. As a PFC, these are your opportunities to separate yourself from your peers and gives you more material to add to your resume and to show the WOFT board members that you have what it takes. Once you've gotten your SIFT and flight physical taken care of and gotten your PT situation straight and created a positive reputation for yourself in your unit then look at your resume and go from there. We can help you polish up your resume but I think you should focus on polishing yourself first (no pun intended).
Good luck and kudos for coming to the right place for questions.
