A ready post box is a box or mailer that you can buy at the post office. The box, for instance can be a 15x12x10 box for $3.19, or a cushion mailer for from $1.59 to $2.09. I think their smallest box is an 8x8x8 for like $1.89. Then of course you'd need to tape it up and label it. You can go to the post office, buy the box, take it home, fill it, tape and label it, then bring it back, or bring your stuff, tape and label to the post office and assemble it all there. Why would you want to do this when the word is full of free boxes? Beats me, but you asked.

Personalized postage stamps can only be purchased online through the post office. The reason you need to do it online is because it is an automated process.
To send something to Germany, you need to provide $1.50 in postage. This will ensure that it gets there in a timely manner and doesn't get returned to you.
That would depend on the weight of the letter. Postage is 42 cents per ounce, with each additional ounce requiring more postage. Your local post office can weigh it for you. Or if you have postal scales you can weigh it, then call your post office, tell them how much the letter weighs, and get them to tell you how much postage it will need.
You need to establish it's overall size and thickness, then it's weight also before you can ask the postage. The post office will be able to do this for you.
