Bleacher prices are too high at the moment, 8-9 dollars should be about right. 8 might sell you out consistently, but you should be expanding your Bleacher sizes anyway and bring that back to a ~90% fill rate through having enough seats to get to 95% sell rate at 8 bucks. It may be possible to do the same at 9 dollars, that's a difficult balance in most D.V leagues I've looked at.
Lower Tier looks fine, 35 would probably do just as well as 34 for your sales but the new setting looks OK.
Courtside seats should be set at around 115-125 for your league. Looks like you've got that set right too.
Luxury boxes are a bit harder since it fluctuates so much in your League but 800-900 is a pretty good rule of thumb for D.V. Basically, you've got your prices set pretty close to correctly already for this next Arena update.
As for staff, I'd recommend picking up a Competent Doctor for under 10K (7-8.5 would be even better) as getting 3-4 week injuries tends to suck and better Doctors cut down those chances. Depending on your training ideas, I'd also recommend popping 5-10K into Scouting. Even if you're planning on placing first, getting at least the Scouting Combine done will help in trying to pick up a decent trainee prospect. 0 dollars is fine for complete luck of the draw, but I'd at least run to 10 points to get that for much better chances of players that fit your training regimen.
