*UPDATE*
Yesterday, I finally started the project. I took an algae remover to it and that got all of the the green off of the sides. Looks a lot better. Then I used the StarBrite teak cleaner. Still, looking even better, so great progress so far. I think I might've ran into a problem and I'm looking for some help. In the pictures below, you will see a bit of splitting between the two sections. I'm wondering if I should fill it with some sort of putty? Also the next step is to sand. Already fairly smooth so would you say 110 or 220 grit? Then it's time to oil her up baby!
