The only thing I can help with is the sound effects. Try looking on eBay or Amazon for sound effect CD's. Or really just surfing Google. there are CD's like 1000 Sound Effects and TONS of those. Type in "Sound Effect CD with _____" Whatever you're looking for. If you use " " it will find it exactly how you typed it. Also try visiting sites like... I dunno, www.soundeffects.com or www.hollywoodsoundeffects.com I dunno if they are real but I do remember looking up some a while back for Dark of the Moon. There are so many sound effects out the, it's amazing.

edit; www.soundeffects.com is real. also try www.soundfx.com.

And what program are you using? If it's Adobe Premiere Elements 2.0 I bet I can help with the other two if I look.
