I am brand new to this so understanding that I don't know anything about anything really would help. I have an old Schwinn continental that I want to rehab. Right now the color is brown and i want to switch it to Campus green. How do i do this and where can i find the right color parts. Specifically looking for the original grip tape and the paint. What is the best way to paint this. Should i hire someone and where should i start looking to get this done. Anything else important that im forgetting? Any and all help would be great.

Those colors are "candy" colors.
In other words, a tinted clear over a silver base.

They are the hardest colors to do well, especially if it's your first frame paint.

My candy red Olmo has all sorts of sags in the red, so even experience is no guarantee with candy colors.

Finding another Schwinn Continental in the color you want will be much cheaper.

So lets see a picture of the bike.

As has been said - don't paint it, just find another one in the color you want.

Agreed. I think the Suburban was available only in your brown and the Campus Green for at least one model year or two. There will be more out there. I have one myself.

Campus Green Conti's are a dime a dozen. Put a wanted out for one in your local Craigslist Bike section, and you'll find one eventually. Always keep in mind that if you find one with nice paint and rusted componentry, you can swap all the good stuff from your existing machine onto it.
