Shoving the sleeping bag in the stuff sack shouldn't take any time at all. My down bag packs down real quick, but my synthetic bags take a little longer. A slightly larger stuff sack might help if your bag takes a long time to force into the stuff sack. I have packed my bivy and sleeping bag into the same stuff sack if there wasn't dew on the bivy.

If you're tent has to be folded and rolled "just so" to fit in it's stuff sack, get a little larger stuff sack for the tent and pack the poles separately in a separate stuff sack.

Other than getting a closed cell foam pad, the sleeping pad takes the most time. I usually deflate my Big Agnes pad while I'm still laying on it and then combine some light stretching as I fold then roll it up.

I like to sleep without a tent on a ground cloth when it is practical. A buddy of mine can be packed and ready in less 5 mins when we're not using a tent. I usually lollygag around a bit.
