Just a comment about knowing the fights. If you youtube fatboss, you will find an extensive amount of videos explaining everything in wow, not just boss fights. Caslir has also posted the videos in the highmaul section. Check em out, they only take a few minutes to watch. Knowing the fights and your role for each encounter will help out towards the first few kills, and to overall progression.
If you need flasks, I have a meth lab in my garrison. Just let me know what you need, and I will cook it up.
