You wanted some feedback, you got one from the master himself
If you want some add-ons, there are a few sites you can go to but the most complete one is
http://www.bigcitybaseball.com/bigcitybaseball/ootp.htm . Under downloads, take a look at "Baseball Sim Central" as they have a lot of good stuff there too. If I can help you in any way I would do so with great pleasure, so PM me if you want. Or you can always post a message, feedback is really quick over here. Great community! (I've said it before and I'll say it again).
