What roster options do you have enabled? Which chapter are you using? A Space Marine Tactical Squad does not have bolt pistol/ccw - they have bolters and bolt pistols.

Is there any way to access these options to change them? I want to add some heavy weapons to my Tactical Squad and use bolters as a default for the other troops.
As shaggai has already pointed out, the grenades cannot be removed because they are basic wargear, and you can only put a single heavy weapon in a tactical squad if you have 10 models in the squad - press the + button at the upper right of the roster view when you have the Tactical Squad selected to increase the number of marines and then the heavy weapon options will appear in the Unit Options pane at the right hand side.
Are you using the 1.06c files (the current ones), or an older versions?
