To directly answer your question: 1. Remove anything you don't want to give to the Linux test system. After all, if you don't know what you are doing (that is what a test system is for), then the Linux image, may be told to take and use devices that the production system(s) want.
2. Remove any "defined but not being used" devices. Like those of us that may have defined some 500 OSA triplits for each of their OSA ports. Not a big deal, but you may spend a lot of time with device sensing and scanning thru configuration files. Or better yet, just give the LPAR "ONLY" those devices you know you want. A few disk drives, a single OSA tripplet, and, perhaps a tape drive (a real one, no virtual ones). Ooops, almost forgot about the HMC console access. I'm a VM bigot, but if you don't have VM knowledge onsite, I would keep away from VM. It will be another layer of something you don't know about. That just leads to more problems. But if you have VM knowledge and/or have someone you can bring in with VM knowledge to get you going, VM takes away a lot of problems and worry.

I was told to remove all of the dasd except what Linux would be using. What else should or should not be included in this IOCDS? Anything else that might prove helpful? We plan to try this with CentOS-5.
