Assume there is a rogue with a base attack of +6.
The rogue has Two Weapon Fighting and the talent
Surprise Attack (Ex): During the surprise round, opponents are always considered flat-footed to a rogue with this ability, even if they have already acted.
My question is this:
The rogue gets a surprise round against an enemy: he can attack once for weapon damage + sneak damage.
What happens in the first round of combat?
When the rogue does a full attack (mainhand/mainhand/offhand) does he add sneak damage to all three attacks?

Only if the enemy hasn't acted yet, or is otherwise denied dex to AC (or flanked). You can sneak attack on all of your attacks if you're eligible, but Surprise Attack only applies during the surprise round.

Unfortunately, it is not possible to take make a full attack during the Surprise Round.
The Surprise Round: If some but not all of the combatants are aware of their opponents, a surprise round happens before regular rounds begin. In initiative order (highest to lowest), combatants who started the battle aware of their opponents each take a standard or move action during the surprise round. You can also take free actions during the surprise round. If no one or everyone is surprised, no surprise round occurs.
Consequently, you may only move or attack during a surprise round so it would not be possible to make more than a single attack, even with the Surprise Attack talent. This talent provides the advantage of making attacks against enemies during the surprise round as if they were flat-footed *even if you lose initiative*.

With the teamwork feat Lookout it is possible to make a full attack during the suprise round, assuming you have another member of the party with this feat as well and you both make the perception check.
