checklist: rope, 13mm arborial static. ascending system, i use a vt system so pulley, eye to eye 8 or 10mm length for the vt knot, 2 3d karabiners. Secondary climbing system or personal lanyard.
Boots
Helmet
Throwline and throwbags (not essential if the first branches are low but it will stop you from having to swap between systems when you are off the ground)
Knot knowledge for what you intend to do, try animatedknots.com if you want to learn any. I would suggest learning blakes hitches, clove hitches, figure 8 on a bight, rethreaded figure 8, bowline, running bowline, distel, larks foot, alpine butterfly, prussiks (there are a few variations of prussiks so whichever makes the most sense and will hold you).
the most important thing you will need is someone with the knowledge to guide you through it in a practical environment so dont worry about going for your cs38 with no knowledge because the courses are designed to give you all the knowledge you need to climb safely. Also i can emphisize knots.... learn them... all knots are good to know and you can practice them whenever you want, the rest of the kit is harder/more expensive to come by.
hope this helps
