1) PvP rogue has a couple different choices. You will (usually) see a Marksman rogue. Ranged DPS with some group utility (debuffs and buff stripping). You may see a couple rangers, they are high damage and just a pure DPS role. Assassins are a Melee single target pressure spec that rely on DoT's. If played correctly they can dish out the damage. Nightblade/Riftstalker is one of the more common melee rogue leveling specs that you will see. Good PvE quest grinding and OK damage in PvP with survivability. Also if you have SL the Tactician is a great soul to use leveling/low level pvping
2) The into souls should have a basic description of the soul and what it is meant to be, so I would read those. If you want more info on the classes, try to post questions here.
3) More bars: Hit Escape, go to Options, Under Interface there should be an Action Bars window. You can add upto 4 on the bottom and 4 on the sides. They can be rotated and moved by editing the Layout under the Escape menu.
