That is quite a lot spent on staff. For comparison, I have a staff total of 52K weekly salary in D3.
For D5, I'd suggest a level 2 doctor with massage specialty, a level 4 trainer, and maybe a level 2 PR guy (I'd go with crowd involvement if you are hard pressed for wins, and national appeal if you're rolling over everyone). The level 2 (basic) guys can be had for ~5K salary each, and the level 4 trainer could be 15-20K, for a total of 25-30K. That'll save you at least 30K per week.
As far as the draft goes, see that thread for the reasons I disagree with CoachSK. D5 leagues are perhaps teh best times to try and get a good draft pick.
