To be honest mate it's a bit difficult to explain how to dive in words.
Best bet would be if you get a paintball dvd, watch how they do it, and then start practicing their same motion but from standing still.
Keep doing this until it feels more natural, now try it with a bit of speed etc steadily getting faster.
As for protection, elbow pads are a must, no box (haven't tried it, but superman slide/box - really don't seem to go)
Knee pads preferably too.
Hope this helps
