You might also consider numbering the parts or make comments as you lay them on a paper towel so you can remember what to do when putting them back together. Also, oil what needs to be oiled and grease was needs to be greased (there is a difference). Also, never put more than a fine coating of oil or grease on anything as there is too much of a good thing and it will effect the performance. I would also recommend cleaning the bearings of any impurities such as old dried up grease/oil/dirt.
