Davidpm gave you some good dvise on your dock lines.
Most people keep the lines attached to the dock rather than to the boat.
This way when you return the lines simple drop over your deck cleats and are at the right length. I would also say that your bumpers be attached to the dock rather than the boat. Makes it much easier for when you are docking.
Do you single hand or do you have another crewmember that can help you?
If you have another crewmember, than some of the things your talking about in many instances can be done while motoring in. Flaking the main and putting on the main sail cover can be done under motor if conditions are right. If you inunprotected waters and bouncing around a bit, than you might want to wait till you reach the dock.
Sounds like you have a hanked on jib. If your simply rolling that up and putting it in a sail bag, I would think that too could be done under motor in realativly flat conditions. Just be very careful that you don't drop a sheet in the water when the engine is engaged. This could be very bad.
I think once you get into a routine it almost becomes second nature and you will start to see yourself getting better at it the more you repeat the process.
I guess our routine is different from yours, our last sail of the weekend is always on Sunday. We usually get back in around 4:00, head to the pool and soak in the hot tub for a while, than go back to the boat, pack her up for the week, and leave around 8:00.
