common questions:
Storage?

Storing wood...What you want to do is provide good air-flow all around the wood, so it all stays at the same relative moisture content. If it's kiln dried wood, and simply stacked (no stickers) in a damp location, the outside edges will start absorbing the moisture, but the inside will remain dry. When it comes time to work the wood, you may (will) have problems. Conversely, if it's green lumber, stacked (not stickered) the outside will begin to dry but the inside will remain wet. Again, you're gonna have problems working it. And it's the 'wet' that attracts the fungus spores (mold, mildew, etc) that begins to grow on the wood.
So, if we must err, then err on the side of safety...Sticker the wood! It's much better for the wood, it will keep it flat, straight and true, and it looks pretty. Those who enter your shop and see a nice, neat stack of stickered lumber, and will be impressed with your professional attitude toward woodworking. Personally, I wouldn't bother covering the stack with a tarp. Just let it breath.

The lumber racks I use are pretty simple. Basically they are 4X4's (I used screwed and glued 2X4's) sitting on the concrete and lagged to the studs with a series of 7/8" holes drilled at about 5deg above horizontal spaced I think about 18" apart. Using 1/2" black pipe cut to 20" long as supports for the lumber. The thing you need to watch is to make sure your holes for the pipe are level with each other.

Storing hardwood...No matter how far off the bare ground, you still will probably design a rack, made of wood. So you basically are ending up with your wood on a collision course with insect problems. You need a very stable,non-wood barrier from the ground to your wood. Do you have access to your attic? Its always best to have attic vents on your gable ends. If you don't, install some and store your lumber up there. Remember,when you go to use your lumber,bring down enough for that one project and let it sit near where the completed project will end up,for at least a week, so it gets used to that environment.

Storing hardwood...The other thing is you do need to sticker it when you store it. The normal changes in humidity will cause the boards on the outside to gain or loose more than the stuff in the middle causing issues. Stickers allow air flow and keeps all sides of the wood at the same condition. a few boards is ok but you have a lot and need to have it stored away from major changes.

Make sure that you build cabinets or buy some old ones. I used the old birch kitchen cabinets from my old house... and I have a rolling cabinet for power tools (routers, belt sanders, 1/4, 1/2 sheet and detail sanders, jig saws, biscuit jointer, drills, circular saw, rotary tool, heat gun, glue gun, etc.) and another one for screws, nails, fasteners, and etc. If you use pegboards to hand everything, your shop will never be neat.
