Avg Disk Queue Length isn¹t a percentage counter. The default scale is 100:1, so a DQL of greater than 1 will appear as 100%. The notes I¹ve seen in the past are that it shouldn¹t exceed 5 on a regular basis, but you should also look at your Disk Transfers/Sec. You shouldn¹t be exceeding 300 or so with the disk layout you have right now, IIRC (110 per disk, count one as unusable for RAID 5 overhead.)
There are some more precise calculations available, as I know my ballparks are probably a bit off. Another thing to keep in mind is network speed. You¹re bounded on both ends by the maximum throughput of the slowest link. If your file server is on GB, but the desktop is 10MB... TCPChimney can be a killer on this.
