Ah, revival of the dodgeball clones.
I remember when I first released that map, a whole bunch of people made dodgeball style maps.
To remove grenades, you need to set the following in your worldspawn:
"paintgrenades" "-1"
"smokegrenades" "-1"
You could also set "forcejail" "1" if you want to force people to go to the jail area, regardless of their jail settings (tip: you can just open up dodgeball.bsp in a text viewer and see the entity data at the end of the file).
As eiii suggested, you could afford to add some more detail into this map. The bunkers look like they were hollowed out of a solid chunk of wood. Try to think of how real bunkers would be constructed -- probably with some kind of frame (maybe 2x4's) with thin sheets of board nailed on. You might take a look at what I was doing with the arctic_dsm map for ideas:

Some occasional support boards running the other way underneath would help the believability a bit, too. At least a big one in the center. Also, the divider in the jail -- that texture is boards nailed to something. With as thin as it is, there's nothing for them to be nailed to. Might want to think about that, too.
Also, you need to make all the spawns face forward and probably keep them further back so people don't get shot at the round start so easily.
I'll go ahead and put what you have up on the beta server for testing. Check your PM for details.
