I make sure to have on hand a variety of lengths of cables, as once you get a rack populated, "too long" is 90% as bad as "too short", unless you've left yourself ample cable management units. (And doing that chews up rack spaces as most theater racks don't have provisions for vertical cable management trays.)
Assuming you have good access to the back of the rack, I'd get 60% 1 meter, 30% 2 meter, 5% each 3 meter and .5 meter for a full height rack.
Disclaimer: I come from an IT background and have seen horrible rack configs as well as working at a place where we literally bought patch cables in 6" increments up to 8' and in 12" increments after that. That said, spending a few hundred bucks on "extra" cables has be something that I have never regretted.
I also make up my own bundles using split-loom tubing. For instance, an SD-DVD player will get a component, a red/white/SPDIF audio, and a Toslink cable all bundled inside a split loom tube with both ends taped and labelled "DVD2". That way, I get less tangling in the vertical cable management hooks that I've retro-fitted to my racks.
That's a real long way of saying "if you can get to the back of it, don't make yourself crazy by buying a whole ton of long spaghetti pieces..."
