1. Get a Service manual if you don't have one. 2. Bag and label fasteners as you remove them. 3. If you are still unsure, take pictures at each stage of disassembly and you can reference them in reverse when putting the car back together. 4. You can always ask questions here too.
My first 2 times I pulled engine and trans together. PITA. I would recommend dropping trans first. This way is easier.
