The various products like "Goof-Off" will liquify the adhesive rapidly, but the mess will spread if you just try to wipe it off. And always be careful about wiping too hard or too long with that stuff, as it has been known to eventually soften paint.
I like to always start with the safest alternatives first and progress from there as required. First thing I usually try is to apply some clear packaging tape to the residue, press down firmly, and then peel off the tape. This will often remove much of the adhesive (may take several applications), leaving much less to be removed chemically. Then I follow up with WD-40, which usually works great for adhesives and stuff like tar. Rather than spray it and get it all over everything, just spray it on a soft cloth and use that to gently wipe away the goo.
When all else fails, head down to your local body shop supply place and ask for the 3M adhesive remover. It's made to remove the adhesive from badges and bodyside mouldings without damaging the paint.

PS I recently removed the factory material from the side covers and replaced it with the 3M film. The original stuff is probably twice as thick as the 3M film, so while it looks better I wouldn't count on it actually protecting the paint from constant rubbing from the seat as well as the original stuff. Keep an eye on it.
