Dodge Repair: Sunroof leaking, marker lamps, water leaks

Question
Morning. I have a 2005 Dodge Mega Cab, 1500 4x4 and I need to remove the interior ceiling panel to gain access to a clogged drain line that drains the sun roof. How? Any web sites that has step by step diagrams for doing this? Also will installing a larger diameter drain hose prevent any future clogged drain lines? Thanks!
