Hi Lucky welcome to the fine art of restoration work. I'm in the middle of mine at the moment. My bike is now completely disassembled and in about 100 pieces. If you are going to remove the engine then make sure you do this before you take off the wheels or centre stand - its very difficult to kep it all balanced and upright without these things. Once the exhaust is of and all the wiring is disconnected and the smaller items such as foot brake pedal is off, I pulled off as many bits as I could to reduce the weight of the engine. Remove such things as the top engine cover, rocker covers, heads and barrels if you intend to replace rings, gaskets, check the bores etc. Front engine cover, airbox, and pull off the starter motor. All ths thins weigh a lot. Finally with the engine bolts removed and the engine supported (I used a car scissor jack and a piece of solid wood) remove the gearbox. You will have to push the engine forward a small amounbt to achieve this.
I have my motor ona bench so i can work at a reasonable height. removing the clutch and or flywheel is okay if you have the tools. Although I'm in Australia I bought a few necessary tools for this kind of work and other things from Cycleworks in the states - great company and good tools.
Once the motor is out and the wiring is off its easy to pull the rest of it to pieces.
In the restoration Logs sectio I and others on thr forum have documented our work often with pictures to help. Good luck mate - keep asking there is a wealth of knowledge on this site and everyone is really friendly and helpful.
