I'm not sure I understand the problem with Weapon Focus, since you can still do Weapon Focus (bastard sword) as well. The exotic proficiency is simply an extra feat to get a +1 average damage bonus higher.
Although, if you ever plan on becoming Large (via Enlarge Person, etc), both 1d8 and 1d10 turn into 2d6 with a size increase, so the bastard sword is kind of a weak choice for that feat.
The elven curveblade on the other hand... nice weapon if you were going two-handed instead.
Regarding the Two Weapon Fighting feats. If you plan on going with the Shield, the Shield Master feat (for no offhand penalties when making a shield bash) has a +11 BAB requirement.
If you expect that 9th level is going to be the peak point of gaming, then you might not see the full potential of the shield bash/twf line.
Not that it won't work for your lower levels. That free bull rush can be real fun.
Note that you don't need Shield Focus to get the Improved Shield Bash effect, or even the whole TWF with a shield line.
Since you are going down the Power Attack line, there some new changes you might find interesting.
Sunder now can give equipment the "broken" condition when they are reduced to half hitpoints. This causes -2 atk and crit only on 20/x2 when done to a weapon, or halved AC and double armor check penalties when used on armor and shields. Wands use double charges to work.
Oh, and the Greater Sunder feat lets you carry over excess damage to the wielder when you break their equipment.
If you plan on playing against a lot of humanoids (city adventure, etc), this could be an interesting option.
With that in mind, all of the combat maneuvers now have greater feat versions. In the case of Overrun and Bull Rush, they make it so the action causes others to get attacks of opportunity against the target. If you intend to be getting free bull rush attacks with your shield slam, and you have party members that will be joining you in combat, then getting Greater Bull Rush is a good idea.
You'll have a lot of feats coming your way (basically one every level after 1st), so you'll be able to branch out quite a bit.
