Someone comment already, I have a similar stalker and I'm trying to figure a good build 
I don't know how much of a fighter you want to be, but I'd be tempted to dump Teleport pool to get the Power Shield and Energy Protection both of those are going to be very useful in PvP, not that Teleport isn't useful in PvP, either that or drop speed pool which you probably don't want to do. If you stick with TP I would swop recall friend for TP Foe.
My own view of Stalkers is they should be able to put up a fight for a time since they actually have excellent defences, despite what most think.
I would put more slots in Aid Self, if you take it I would go for 3 for heals then any more you can fit for interrupt and/or recharge. I took Stimulant rather than Aid Other since Heals are more common than Un-Mezzes in PvP. Both Aid Other and Stim are extremely tricky to use when you're fighting though.
How does this look for a PVP/PVE build guys n gals?:
