Thanks in advance for your help!

The general process is to nandroid backup all partitions before making any changes.
The /data partition holds all application settings and all android settings.
The process to install a ROM, reboot recovery, wipe /data and /cache. Wiping /data will wipe dalvik-cache, battery stats, rotation data, etc.
Install the ROM and reboot. First reboot will take a lil longer as android rebuilds your dalvik-cache.
Now, if ROMs share the same base, i.e. you switch from one sense based ROM to another sense based ROM, you *might* be able to get away with not wiping /data. It really depends on the details of the previous ROM loaded and the new ROM loaded. But if you switch from a sense based ROM to a real AOSP based ROM (example: CM7), you will definitely experience bootlooping. Hence, it is commonly best practice to wipe the /data partition whenever switching between ROMs as it will remove any possibility of bootlooping from /data issues.
Hope that helps!
