Okay guys help me save myself from myself. I am looking at picking up a JRB 8x8 tarp here is the product description:

"Description: The ideal backpacking hammock tarp for small and regular size hammocks. Made out of silicon impregnated 1.1 oz. ripstop nylon cordura® with ten tie-out/lift tabs. This tarp with its diagonal ridgeline seam was originally designed for hammock use and requires only two stakes. The 10 foot diagonal ridgeline provides excellent coverage, including full side wind protection, for hammocks up to 9 feet long. It readily facilitates ground use for those seeking more width than traditional 5'x8' tarps or ponchos. The tarp finished size is 7' 2" x 7' 2". It weighs 9.4 ounces and packs to 5"x5"x2".

Okay do I still need to get a cord for the ridgeline or is it included? I know I need some tie outs how many should I get?

If you were buying this tarp what other extras would you pick up?
