Weeeeeelcome to Incursion.
If you're not familiar with d20 systems and the general strategies used in them, you'll have a pretty hard time; that said, it'll still be very fun.
So bard builds. Bards are a bit problematic in general because their spell and skillsets are geared towards rolling with allies, which are not fully implemented. They're difficult to recruit, pretty squishy, and do various things that ruin your day like taking your loot, walking into suicidal situations, or killing things and making you take the alignment hit (If you haven't turned off complicity transgressions, do so now). They're kind of a challenge class at this point. Multiclassing might make it easier, but I wouldn't know how to go about that; probably take one of the summon-proficient classes (Druid, Priest, Weavecraft Mage).
For your skill point distribution, you want to focus on the core skills, which for you would be are Diplomacy, Concentration, Perform, Healing.
There is a bug with Disguise: if you use it before you have enough ranks to totally avoid the penalties, they become permanent. IIRC you have to be somewhere around +15 to use it safely. In any case, it's not particularly excellent; there are a few themed vaults which it's useful for (Illithids, mostly, and orcs before you're ready to take large groups of them), but I wouldn't use skill points on it.
As for feats, it's best to take those that grant non-numerical benefits; you get enough skill points to make the skill-boosting feats completely obsolete by L3 or so, unless you have very low int and are playing a low skill point class, which Bard is not. That said, some of the boosters give auxiliary benefits like Acrobatic's no-AoO jump (which you can use to disengage without contest), so if you can make use of those, do.
As a caster you'd want to at least take Combat Casting. Take Leadership for the extra CR pool. Maybe take another defensive feat; Expertise is useful if you pick up something with very high parry (ex. scimitar), which is a free +6 DC if I remember right. You might want Counterspell and maybe Reflective/Broad Counterspell when you level up.
