@Golem Talents are the same methodology as skills etc I listed above. As far as Talents, let’s say you have 20 Focus on Wizard chest in PvE (those scale from PvE to PVP). This would correspond to 4 Focus Talent in PvP. You can look at the gear in PvP and visually see this. If you add epic Talent on a gear, for example 10 Focus, then it will become 2 or 3 Focus in PvP (depends on the roll - just use the process I listed above to Maximize). Hope that clears it up.
You are also correct in interpreting what I have described about PvE Hero Points not being applicable in PvP, unless you have those affixes on your gears.
