Your ability scores don't increase at level 2. You get an increase next at level 4.
You can buy lots of things with gold and some things with Prestige. I'll assume PFS from here.
If you have 6 Fame in PFS you can buy any Always Available item (almost any mundane item and some basic magic gear), any item on one of your chronicle sheets or any legal item that costs up to 500 gp. No, it really doesn't get much simpler than that, you are expected to read the Guide.
You probably have about 1500 gp, so you might want a masterwork bow and the best light armour you can get. If your Strength is not high, your bow doesn't need to be expensive, so you can probably afford a mithral chain shirt (1100 gp).
You might think about saving your Prestige for emergency fixes that can't be bought with gold - starting with 5 PP for body recovery - but if you want to spend them, you can get a legal item costing up to 750 gp for 2 PP. One of these might be a wand of cure light wounds, which most bards can use. Another might be your improved bow.
