Tailspin, for bard builds you should determine what you are doing while everyone else is fighting. Standing around twiddling thumbs...no good. :)
One of my bard builds, relatively simple:
Human
Str14 (5pts)
Dex14 (5pts)
Con12 (2pts)
Int14 (5pts)
Wis8 (-2pts)
Cha14+2 (5pts)
Don't worry about the Wisdom score, it wont affect much since your social skills are Charisma based. Even Sense Motive (for you) will be Charisma Based at level 2.
Feats:
1) Combat Reflexes and Bodyguard
3) Lingering Performance (spend only 1 round of bardic performance for 3 rounds of it. But you must restart it every 3 rounds).
Skills:
Full ranks: Performance Oratory (Diplomacy and Sense Motive), Performance Comedy (Bluff, Intimidate), Perception, Linguistics
Every even level ranks: Knowledge Arcana, Dungeoneering, Local
Every odd level ranks: Knowledge Nature, Planes, Religion
Every 4th level ranks (you choose the order): Engineering, Geography, History, Nobility
Total # of ranks required: 8 per level. Because you get bard bonuses to your knowledge checks you do not need full ranks in knowledges to stay on par with other classes. The knowledges I listed as every 4th level do not need a lot of ranks usually, so you can get by by putting only 1 rank in them every 4 levels. The Performance skills cover your diplomacy and Sense Motive at 2nd level and your Bluff and Intimidate at 6th level.
Weapons: Longspear, Shortbow and dagger.
Use the longspear or to trip medium opponents whenever possible. Due to Bodyguard you are going to be boosting the AC of whoever you are standing behind. A Whip is not helpful here because you do not threaten with a whip.
Stand behind your fighter and stand behind him always. Anytime anyone attacks the fighter you use Bodyguard to try to add +2AC to his AC.
If you are using the optional traits rules at the back of the Advanced Players Guide, take the trait Adopted in order to take the Halfling trait Helpful (Halflings of Golarion book). This increases your Aid Another to +4AC.
Use control spells normally. :)
If you do not want to go the Combat Reflexes +Bodyguard route I would suggest the archer route. Pretty much the same exact build except for 1st level take the feats Point Blank Shot and Precise Shot. Level 5 take Rapid Shot. Also put the +2 human bonus on dexterity instead of charisma.
