Is it better to change transmission oil AND filter or just drain the oil and add fresh oil??

2007 Cadillac DTS Performance engine - I hear changing the filter in this car requires the removal of the tranny - Right?

Better to change both the fluid and filter (if equipped). The 4T80E transmission has two filter screens that are serviceable - inside the oil pan. These are removed and cleaned during the trans service. No need to remove the entire transmission for the fluid service.

Just drain the transmission normally via the bottom pan, or by using a suction pump and hose length into the fill plug hole on the side of the transmission.
