Keep the weight low. Tee Bags are nice but they carry the weight way to high.
Use only water proof bags to keep you stuff in.
Buy light weight back camping stuff. Stove, single mantle lantern, nesting pots, and a light weight Gerber Axe. It's expensive but it will pack small and light.
Get two light weight sleeping bags. I use 2 40 deg down bags. They work well in the heat as well as down to the 30s. Use a self inflating sleeping pad. They insulate well from the cold ground and do a pretty good job of keeping your backside off the ground.

makes some good water proof bags as well as a good set of straps to tie it all down.
Pack an extra stuff sack to use for your pillow.
Go to your local sporting goods store and get a tent that suites you. Remember if it's raining all your stuff will be in there with you AND you have to get dressed and pack in the tent if it is raining. I've gone through 4 tents and finally have two that I sue depending on the expected weather. (REI Camp Dome for nice weather and a Sierra Designs Orion for the cold/wind/rain possibilities)
Buy the "high performance" type of underwear. It washes easily under any faucet and drys quickly. Get a mesh bag to top load to dry.
If you want to do a LOT of camp cooking get yourself a Collapsible Ice Chest and buy your food for the night at the last stop before setting up camp.
I've been refining my camping set up for MANY years. I do motels every couple of days and camp the rest of the time unless you find campgrounds with showers it's make a motel every couple days a necessity.
That's the Sierra Designs in the backgrond. This was my KTM. The red case on the seat holds my stove and my lantern. The bags on that bike hold just a little more than a Harley Bagger.
And last but not least, get a comfortable chair. Most any of the cheap Box Store packables will work. Makes drinking around the campfire much more enjoyable.
And last, pay attention to what you use and don't use. Don't pack the stuff you don't use on the next trip!
