I sit possible to program the DJM800 to control or "trigger" cue points or things liek that in Serato? If so, how can this be done? If not, what can I buy that will allow me to do this?

Yes, you have to MIDI map what you want the SL to do and what triggers will be used on the 800. I have seen a video where the user has the fader starts do loops and cue points in SSL. Set-up the MIDI in Serato and point it to the 800 by attaching the 800 through a MIDI cable and turning it on. Also try their forums for more help or google for vids. let us know if you set it up...
