IPAD Opinions about case and smart cover for newest IPAD

I'm getting a new IPAD soon and am trying to figure out the best case set up and wanted some opinions.

I haven't used a Ipad yet but my plan is to get a Apple smart cover and then use a clear back cover that works with the smart cover or use the Zagg Shields plastic film on the front and back along with a smart cover. I'll probably get some sort of sleeve to carry it in when I travel but in general are the smart covers recommend and are they recommended with a case on the back and/or a shields type protective film? I don't really want to get a big bulky case for it. I don't think dropping too much of a worry since I will be seated 99% of the time most likely.

I need a keyboard too although I won't use it all the time but does anyone have a suggestion on a good small keyboard that you can recharge and it gets a long life span off one charge? Or better yet is there a KB that will use the Ipad for power so you don't have to fool with batteries or charging?
