No questions are stupid. We are glad to help.
Loading/treestand: I suppose you want to cock it before you climb your tree...then load with bolt once you pull it up to your position?
I prefer to cock mine before I climb. Just safer that way if using a rope cocker. With a crank, not as big of a deal. If pulling your bow up after it is cocked, make sure no arrow is loaded and do not grab the bow anywhere near the path of the string.
Unloading..I take it you need a target to unload..though hate to "waste" shooting a bolt at a stump while out hunting and no target available (bring a "junk" bolt for this maybe?). or do you manually uncock it? and what is process of that, seems dangerous.
Most crossbows will need to be fired to unload them. Excalibur, Kodabow and CamX can be decocked manually. There is a great video on Excaliburs site on how to do this. With other bows, you have to use a junk arrow into the ground or many companies are now making small portable discharge targets for this purpose. Also, there are arrows specifically designed for discharging crossbows. They are heavy and heavy blunt ends so they will not bury in the ground.
Broadheads: Can I use the 125 gr broadheads I use for hunting with my bow? or do they specifically make them for the bolts.
Regular broadheads will work just fine in crossbows with the exception of some mechanicals. Because of the rapid acceleration stroke, some mechanicals will deploy their blades prematurely resulting in iffy accuracy or the blades hitting the foot stirrup. If using mechanicals, safer to use ones that saw "crossbows" on them to be sure.
As for weight. If your arrows have aluminum inserts up from, go heavier. 125 and up to increase the front of center balance. If you arrows have brass inserts, 100 grains is perfect.
Bolt nocs: there seems to be 3 diff types of nocs for the bolts. What is difference? I suppose they may vary with xbow manufacturer ....
There are moon nocks, similar capture nocks, flat nocks and a new universal nock called the omninock. Each manufacturer has it own recommendation so follow those. Generally, it is safe to shoot omninocks and moon nocks out of any bow, though. It is not safe to shoot flats out of bows designed for moons or captures.
You are welcome and best of luck!
