How do U put perfectly intact samples into FruityLoops?

[MelFunk]

ok... today i put Nuttin but a g thang into Fruityloops, but it got cut into 64 beat samples. How do i slice the part of da song i want all together? How do i make it sound better...(i can't hear the flutes and snare dat well?) and if i can't download da whole section and i get 50 beat slices for all songs... how do i make the song sound synchronized? the slices pause in between each one.

Also, what are good programs that i can record my voice and freestyle on?... i heard of Cake Walk!... and can I put my audio freestyles into fruityloops and if not, how do I put them together?
