Bicycle Mechanics - Help on rear bike rack install on disk brakes

Edit - I have an Axiom bike rack and I have attached pics of gears. Thanks for help so far. This is the bike rack I have
Hi I have a Giant Cypress DX and I am trying to put a rear bike rack on. It came with 3 of the same screws and one longer screw with a washer and nut.
1. Where do I use the longer screw with washer and nut?
2. Standing behind my bike and facing forward, which threaded hole do I screw the bike rack into on the left side? The only obvious one has my disk brake mechanism screwed into it and I dont want to mess with that one.
Any help or links to video or pics is appreciated.

can you tell us what bike rack you have? pictures would probably help.
Without knowing what you have it's really hard to tell but there are generally racks available specific to frames with disc brakes (or adapters that would have come with). Typically the location of brake calipers requires a standard rack to not fit at the dropout.
Here's a rack that's designed to fit around disc calipers:
Here's the same rack in the standard configuration:
Anyway pictures of the dropout of your bike and the rack would be helpful. We have a few years old giant cypress disc here and the mounting holes are right near the quick-release skewer for the rear wheel. The other holes on the seat stay have a rubber plug in them that you need to remove..
Good luck - i hope this helps!

Thought about this again and it's possible that the long screw and washer (is is a long washer?) are meant to mount the rack around the caliper. If this is the case then you want to mount the long washer between the rack and the frame.
From the outside:
Rack -> Washer -> Frame :: the screw goes through the rack and washer into the threaded hole in the frame.
The other 3 screws would be used to mount the other 3 attachment points of the rack.
Thanks for your reply. I am not sure if you get notified when I edited my original post but I added a link to the rack I have (an Axiom) and pics of my bike dropout. I appreciate you taking another look and telling me which threaded hole I use on the left side of my bike.
Click on the link:
Your frame is designed to have the rack mount in the hole between the caliper mounting bolt and skewer. I certainly don't like the fit of that rack in your pics.
