How do I select which talents the Select Talents option chooses? I want to choose my own ones so that I don't need to switch out anything. Thanks.
Hell no. Especially for PvP. And even when playing PvE, there is no one talent tree that is the best. There are many different talent builds that fit different play styles/preferences.
You can edit the xml file (or create a new one) under <Honorbuddy root>\Data\Class Profiles for your class and spec. The format should be fairly self explanatory.
