3 mages or 2 mages 1 priest for dps team

I could use help on professions myself.

I planned on Engineering for PVP for all of my main party.

I plan on Blacksmithing for the Glimmering Mithiral Horseshoe on both Paladins.
I think I want 1 disenchanter in the party as I don't have a warlock in my main party.
I then wanted 1 of each main resource skill in the party (skinning,gathering,mining)...

If my math is right that is 11 and I only have 10 slots so I got to give up at least one so which one?

I also don't know if there are other/better choices for PVP in general or that are key in PVP for Paladins, warriors, & Druids?

Also don't know what I am giving up PVPwise by going blacksmithing for the horseshoe trinket... Maybe that is overkill.

The reason I wanted one of each gathering skill was because I planned on turning on resource tracking and treasure hunting and find undead on specific dedicated main party characters and then use ISboxer's VFX to pull those tracking to my main foreground client. That way I can easily grab everything I can so to maximize gold making potential...

As far as the rest of the professions I plan to do at least one additional 5box team to 35+ (maybe more) for the passive cooldown goldmaking professions and then dedicate them to any professions I want to have maxed but not necessarily on my PVP mains.

Any help or thoughts are appreciated as I am not sure yet...
