How will these factors affect my application?

I’m applying to Oberlin ED, and wanted to know how the following things would affect my application, if at all.

Being able to pay tuitition up front.

Average high school ACT score. (Between 18-21 at my HS, I got a 31)

Percentage of students that plan to go to college (About 60 percent of my class are planning on 4 year, 20 percent 2 year)

Also, does anyone know how grade recalculating works at Oberlin? How important is GPA to them? I know US NEWS etc says “very important” on the website, but is it really the top priority? I have a 3.3 with almost exclusively honors and AP classes, and I know that is below their average (3.5). Are the averages GPAs listed on US News etc before or after the grade recalculating?
