The best fit for your concept is a human-form only, imo. And if you've never played one before, it means less investment in needing extra binds/macros for form and bar switching.
Also, TP is the WS's built-in travel power and it works well if you don't want to dip into an extra pool power just for travel. I use this bind for TPing around: /bind mousechord powexeclocation camera:max teleport
Hold right mouse button, rotate camera to aim, click left mouse button, teleport straight out as far as you can.
Edit: Also, WS's and PB's both benefit most from being on teams; you get buffs based on your teammates' AT's, so you're likely going to want to be teaming.
