In a nutshell I don't think you can go wrong with:
Pages
Numbers (not tried it but if it's as good as Pages...)
Reeder - easily the best RSS reader
River of News - 2nd to Reeder
DropBox
Goodreader
I also recommend PasteBot - lets's you store snippets from your clipboard to use later in your Pages documents or anywhere else you want to paste
I would highly recommend MobileRSS HD for the iPad. I have about 8 that I'm testing and this one is still the best.
Also, yes. Pages is simply fantastic.
I'd recommend WordPress, but I've NEVER been able to get it to work.
Pinball HD
Infinity Blade, fo sho!
Awesome Note is out for the iPad now, and it looks good.
