I wanted to remove some actors from game not familiar with GECK can anyone give me some directions?

Also would this work for the STEAM version of fallout new vegas?

What actors are you referring to? We're going to need more information but, removing, deleting vanilla ref's can be very dangerous. If the actor is needed for a quest or, another mod relies on them you could end up with a glitchy mod.

All versions of FNV are STEAM versions so, this is a non issue.

Just deleting vanilla actors really i just need to know how to remove them from the game all together they arent essential to the story and i dont want them ingame

Would markfordelete get rid of them?

You could use FNVEdit to disable the ref(s):

• Open FalloutNV.ESM
  
• R-Click FalloutNV.ESM in the left panel > "Build Reference Info" > FalloutNV.ESM > OK
  
• After you see "[01:08] All done!", find and select the NPC record
  
• Click the "Referenced By" tab in the right panel
  
• Select/Multiselect all ACHRs in the right panel and R-Click > "Copy as disabled override into..." a new plugin.
  
• Close/Save

-OR-

Add a script to the NPC record:

Begin GameMode    If GetDisabled        MarkForDelete    Else        Disable    EndIfEnd

Either should work. Might want to do both if the NPC is referenced by any LVLN's or, even better, modify the LVLN to exclude 'em.
