Good generic DSCP Code point map

We have an aging network of PMP100 radios that are gradually being replaced by PMP450's but we would like to do something to alleviate congested PMP100 AP's by capping bandwidth but allowing SM's to burst to higher speeds momentarily.  I understand that part.  What I would really like to do is impliment a QoS regime that will prioratize traffic.  I have an idea how diffserv works but having a hard time finding how types of traffic map to code points.  Are there any good generic maps that anyone has developed that works well for your customers and would be willing to share with me?
