DBF/LWF file creating; chopper glitch

[CROCO]

Hello everyone)
I have been making my new map, but I faced with few problems. And I want to receive some advice from more experienced mapmakers.
The first problem is custom music. I have 5 .WAV files with music which I want to insert into my map. I found out that it is possible to do it via combination of DBF and LWF files. Moreover, I've downloaded LWF Builder. But I didnt find any tutorial about how to make LWF or DBF files. So, yes. I need some help.
And the second problem is weird helicopter glitch which happens in DFBHD: if somebody shoots the static chopper, it moves forward. And it totally ruins landing in my map because helicopter (which under heavy fire) lands in random place. But I want to land it in certain place - in small helipad. So yes. I need some help with it.
