Welcome. My first recommendation would be to do a search on this very topic as many of these questions have been asked before. I'll try and tackle the rest:

First is our mattress. I have read that American bed standards are very different from European standards, and that we may not be able to find a mattress that we like. Ours is very new (<1yr) and was about $600, so we are thinking of shipping it. Is this true about mattresses in Germany--that they are not as nice/thick/soft (not sure what the differences would be) as American ones? How can I assess the likely replacement cost for something comparable?
King, queen, twin, etc. don't exist here. The beds are standardized in various sizes but sheets form North America won't fit here and vice vesa. I prefer my German foam and slat bed to a traditional box-spring and coil mattress but I'm weird like that. I like it so much I'm shipping it back to the US with me (in about 2 hours no less). Most North Americans prefer what you have. Everyone agrees that German pillows suck.

What about electric appliances and such? Mostly I am worried about my KitchenAid, which I would be terribly sad to leave behind...also have a waffle-maker and ice-cream maker that we use quite frequently. Is there any sense in bringing these kinds of things? Would they work with an adapter? Prohibitively expensive to replace?
I can almost guarantee that those appliances are 110V/60Hz only and won't work here. You could use a transformer which would be a real pain in the ass. As for being prohibitively expensive to replace? Yes. KitchenAid mixers go at an outrageous premium here. I've seen them for 1000 Euros in department stores but you might be able to find them cheaper someplace else.

Last is about clothes. The aforementioned 10-month old was responsible for some shifting and repositioning of various portions of my torso, and I am going to need to purchase some clothes--especially work clothes--soon. Given the weak dollar, it seems like it might be better to shop here before I leave. Does that seem like it could be true? I mean, other than the obvious Levi/Wrangler thing. Also it sounds as if there are fewer "bargain" or outlet-type shopping places in Germany. Is that true or have I gotten the wrong impression?
Buy what you can now and bring it with you. There aren't fewer discount stores here, they're just different. The Target/Wal-Mart/K-Mart type store is a rarity here but you'll find chains that sell on the cheap.

Well this is only the tip of the iceberg...I have a million more questions: childcare, professional networking, learning German at 38, maternity leave benefits, health care, etc., etc.--but I will try to keep them in their own threads. I'm pretty excited to be moving to Germany--I have always had a great time when we have visited--but I'm also a wee bit, um, terrified and intimidated by the logistics. Particularly with the baby.
Most of us have been there before. As you arrive, I'll be leaving, and so the cycle continues.
