Need info on filming pirate movies

I have a low price samsung digital recorder.  I have done a few movies w/Final cut pro applications.  I have an imac G5, can anyone give me some better techniques as to filming these movies?  I did a detective. "Film Noir" type movie, but had some techno difficulties, the sound tracks,  This was largely Due to we had to use the college computers, and the college kept relocating the computers so, I lost a lot of the editing effects the instructor had assited me with.  That was a tad bit ago, now I have a good mac computer at home. Does any one Savvy how to work on film work?, remember I am just a college student

thanks
