To get more information (and more money): take a few hours with all of that stuff and try to set up all sets and dust them off. Then take some good photos from different angles. Measure all diameters of drums and cymbals. These are given in inches, so divide centimeters by 2.54 to get the size in inches. Then round off to the closest number.
For the cymbals, try to post weight, diameter and a few photos of each cymbal: front and back, stamp, middle hole and problematic spots - you'll need these for the sale anyway. If you show us one cymbal per post or give them numbers, it'll be easier to reference all that stuff.
This site gives you some great advice what matters to buyers of drums and cymbals, so find out if there are any big problems:

You don't want to state that a set is in great condition, ship it somewhere and then the buyer is (rightfully) mad that there are lots of problems.
On the other hand, you don't have to say "I know nothing about drums" because people might try to abuse that or refrain from bidding.
Luckily, measuring diameters, checking if screws are tight and most other things can be done even if you're not a drummer.
By the way, since you're a bassist: I'd consider keeping the Remo set, the snare with the Pearl strainer (probably self-made?) and some hardware and cymbals. Those drums won't sell for a whole lot, even though it's potentially a very fine set for rehearsals at your place.
