Also, I need some late-game Maokai pointers. Anyone play him much?
I keep leading the team in damage while being the tank but have lost all 3 matches I've played with him.

For example. I picked up a late abyssal because I wanted more MR but couldn't justify an Spirit Visage, but I can't seem to do enough to help the team win. I try to keep the ult up around teammates, but the damage reduction never seems to be enough to keep said teammates alive. I often find myself alone with adc's and mid's dead because I simply couldn't peel for them enough.
Any insight would be appreciated.
I play him very often, (about win rate of 40% to be fair which is not good) but my problem with Maokai is exacly the opposite of yours. My early game sucks and can't farm due to other top laners being aggressive without needing mana, but my late game is pretty good and tend to win games even if I am behind kills and CS.
your build is sort of wrong. Maokai have a healthy scaling when it comes to Def/HP and what you need (and make it a priority) is 40% CD and Mana. He is very Mana intensive champ and you will need lots of it. His cooldown is long and you need to keep spamming abilities for CC and for your passive to be useful.
What I do is build Tank on him 100% unless I am ahead by far and get 1 AP/tank item. So for Def, mana and CD you need Frozen Heart and Spirit Visage for MR and take better advantage of your Passive. The rest is situational. Ruindon against bruisers/ fed adc and Warmog with champs who have high dpc and burst. Abyssal is not helpful really because you have Warmog for HP and you can get Rod of Ages for AP which also have Mana and HP scaling.
The way you play is also situational and dependent on the team you have. If you have a supp who can peel, use your W for engaging and targeting. You are the tank so you need to engage and point out the squishy ones, luckily the range of that is pretty good, and you can normally land an ADC simply by just walking to the group of enemy you are facing. Your Ult is very powerful and your teammates need to take advantage of that and burst the other team to hell, but that needs a coordination more than anything.
