Str8.150 (Turntable) Setup?

So I was wondering what else would I need to connect Str8.150's to Traktor or Cross DJ.
I plan to put the input of the turntables through my Mixvibes Control Pro first.
I haven't ever used actual vinyl turntables before so I'm not sure what all the requirements are.
Maybe I should invest in a larger controller instead?
I want to be able to scratch. With the str8.150s or other type of vinyl turn tables, would I be able to use them to scratch any sound clip of my choosing?
Any suggestions / ideas?
Thanks
