In terms of your funding, while you have 300m, you may need to save up more if you're looking into a +8 +16% Okas set [as a warning, they're also relatively difficult to find] .. such an Okas set is ~350-400m, depending on how many people are looking into a set. This about how much the Oska set is, as well.

A +6 set will be more around 200m.

As for your bow, GBow is around 75-85m now on the market. Unless you're going to be using the GBow for gianting, I don't see it as a necessity. Finding green weapons may be a good way for you to earn money, however, so it is something you can consider. I highly recommend selling it and buying an HBow later, though, just because of your funds, and how it will be better for you to invest money into a good set versus a GBow.
