No one can answer those specific questions, legitimately, without doing a full evaluation of your team league.
Training is important. Get high quickly.
Coaches are easy if you've played awhile and don't sweat 73 instead of 76. Just be comfortable.
I tend to focus on HS or college but not both. IFA is a wild card. Expect to spend big prospect money to get a top IFA.
If you're going to chase FA, budget 15-20m more than your current payroll. Good ones will be expensive.
