Check out Jamey Aebersold Play-a-long books/CD sets.    Even the best trumpet players have some lying around.  Use them in your daily practice to keep up your jazz chops or learn new changes.  Look for them in your local music store.

In the old days there were lots of jams where you could go to practice jazz licks.  Today, they are few and far between. And that's where Band in A Box comes in.
It's a software invention of a little company in Canada.
You simply download the software to  your computer, install it, and you've got instant band accompaniment for virtually every standard or jazz tune ever written.  The web is full of BIAB files. Go to http://www.pgmusic.com/
and have a look yourself.  A great tool. 

I'd be remiss if I didn't single out Trumpet Herald - the trumpet player's home on the web. http://trumpetherald.com/. Some of the best trumpeters in the world take part in its forums. Expert advice is offered on how to overcome the many obstacles towards excellence, whether it be breathing, tonguing, endurance, range development - you name it, they've tackled it!  Another forum is
http://trumpetmaster.com

Consider joining the International Trumpet Guild. The non-profit group boasts more than 6,000 members - professional and amateur performers, teachers and students - in 64 countries. Members receive ITG quarterly journals which are chock-a-bloc full of articles of interest to trumpeters at all levels of proficiency. Its annual conferences are 'must attend' events by top classical and jazz trumpeters.  http://www.trumpetguild.org/
