How far can the trap be from the washing machine? The trap now is about five feet from the waste line and the machine is next to it. I want to move the machine 10 feet from the trap, but don't want to relocate the trap. Is that OK?

Is your washing machine front-loading? I know some (many?) front-loaders have mildew problems because water gets trapped around the seal. Cleaning the seal and leaving the door open when not in use may help.
Ideally, you should move the P-trap upstairs, and vent through the roof. Under no circumstances should you have two p-traps in one line. You get an air-lock between the two, and funny stuff happens.

Typically washers discharge into a standpipe, which extends 18"-42" above the trap weir. The plumbing can then continue on 5'-8' before there's a vent (5' for 1¼" pipe, 6' for 1½" pipe, 8' for 2" pipe).
