You're a human, and a paladin. Put the 5 in Int. When you only get 2 + int skill points, anything below Int 8 doesn't actually hurt you anymore. Then, between Human and favored class bonus, you can still get 3 skill points per level.
Sol's stat array is probably the best. And yeah, that's a horrible set of rolls. Did Pathfinder get rid of the 3E rule that "if the sum of all your bonuses and penalties adds up to less than +1, you get to call bullshit and reroll the entire set"? Because that's totally a rule, and your stat bonuses right now are +2+1+1+0-2-3 = -1.
As a Paladin, and one with poor stats, you should give up any dreams of archery or TWF. Sword and board is as bad in PF as it was in 3E, and having both becomes problematic when you actually want to cast a spell or use lay on hands. So go 2H style. You are the party tank, and the most effective way to do that is to do a lot of damage so enemies must pay heed to you. Your defense may be lower, but therein lies one great advantage the PF paladin has: swift action self-healing w/ lay on hands. It may seem selfish, but unless another PC desperately needs one of your mercies to clear a status effect, never waste a standard using LoH on someone else, nor out of combat. Save it for yourself for the better action economy. Make yourself a big enough target by damage-optimizing that being selfish with it is justified.
Beyond that, uh...general advice...
1. Power Attack is good.
2. Fey Foundling feat with LoH is pretty decent. 1st level only feat, though.
3. Eldritch Heritage can totally be worth it. Either pick Arcane bloodline for a familiar, or if you can wait for 11th level and Imp. EH, pick Marid for an unlimited use 60 ft line area of effect attack that does damage and BLINDS foes. To round out your arsenal.
4. Once you can get Mounted Skirmisher at level 14-15, the Saddle Surge spell becomes pretty incredible. Before then, the spell is great with a bow. And you can always dip Sohei Monk to get Mounted Skirmisher *extremely* early.
5. NEVER EVER take level 20 in Paladin! Dip out! The capstone makes your primary class feature completely worthless against the foes you most want/need it against. It's appalling and embarrassing that after years of being out, paizo still hasn't fixed this problem.
EDIT: 3.5 PHB, page. 8
If your scores are too low, you may scrap them and roll all six scores again. Your scores are considered too low if the sum of your modifiers (before adjustments because of race) is 0 or lower, or if your highest score is 13 or lower.
If you do get saddled with horrible stats, I suggest you shelve the Paladin plans for another game and instead make a Synthesist Summoner. Ultimately, all that character cares about is charisma and moderate constitution. The rest is largely inconsequential.
