IDE cable... I'd go with flat rather than round, as the electrical properties of the round cables can be rather uncertain, and not too much longer than needed.
Drives - eek!
I'd be surprised if any drive in that list is not DL
I'd rule out ones that don't get a lot of attention here, or ones that rack up a lot of bad points in the attention they do get, but I really wouldn't want to call it, guess if I had to make a snap choice now, I'd be inclined to plump for one of the pioneer 111 drives (though I'd rather wait for the 112), or maybe a Liteon with 20X speed (not for the speed, but just to be current and with firmware/media code updates for some time). Actually, that seems to be a negative for Pioneer, they seem to be pretty slack in media code support, and pretty sharp in retiring old models from updating.
