I use some things from both epel and rpmforge on many systems. However, 
I have used the yum confs to enable what I need from one and exclude 
everything else. Then if I'm worried about the other having what I'm 
pulling in from the one, I disable that in its conf file. You should 
read up on the power of yum where you can set priorities, do exclusions 
and such.

Yes, you can get into trouble if you add 2 without any control. For 
instance, something like clamav. One repo might set it up with the 
username of clam while the other might use clamav. As the updates come 
down, suddenly it dies and you have to figure out that the logs are 
owned by the wrong user. This is just one example of many things that 
can go wrong with mixed repos.
