(I tried to paste the recipes in, but the forum doesn't like them. You can look them up in NEI. As of right now, the pages on the Feed the Beast wiki are accurate, also.)
The chests are a bit expensive. 2 obsidian, 4 blaze rods, an ender pearl, a chest, and a piece of wool.
After the chest is placed, you will see three colored bits on top. You can apply dye to each bit individually, creating a code to identify the chest. It is possible to make a chest private by clicking on the latch with a diamond. This will consume the diamond, but it also means that someone else making a chest with the same color code cannot access your things. Given the general nature of the TOG servers, I tend to think this is unnecessary.
A pouch requires 4 blaze powder, an ender pearl, 3 leather, and a piece of wool.
If you right click on a chest with the pouch in your hand, the three dots on the front will become the same colors as the bits on top of the chest.
Right clicking with the pouch selected will give you access to the contents of the chest, no matter where you are. If you die or lose the pouch, the chest is still safe at home where you left it.
I made a couple of canvas bags. They take a stack of string each (8 canvas, each canvas is 8 string surrounding a stick), but a flax farm makes that simple.
Each canvas bag holds as much as your player inventory. Right clicking with the bag selected in your hotbar opens it up. Fill them up and put them in your Ender pouch for lots of safe storage.
