Yes, you can. You need add wanted templates only once per forum. It doesn't take so much time, while testing I have added thousands of them :D I can't reproduce this. For that forum enter a "Prefix ID" as "dl" (without quotes). And for DD you can trick it a bit: If you use let's say "Filesonic" as your prefix, then select that forum, and where is "Filesonic" tag enter "DD" , then mark "Use prefix as a tag in subject". So when using "Filesonic" prefix a DD will added to the subject for that forum. 1. Yes, you can. (not more though). 2. You can't do that at the moment.
