New AA1 - some questions

Hey Guys,
I just bought an Aspire one with linpus preinstalled. I like the userinterface so far. I want to use the netbook for mobile browsing, mailing, openoffice, twitter, blogging, im, webdevelopement and backing up the pictures I made with my iphone.
I activated the advanced features and think I understood the concept of that Packed Manager: It is a little registry of installed software and software I could install and on top it can open archived files ending with rpm and should handle the installation.
So I installed Skype, that worked quite well. Than the firefox 3, that worked aswell. (http://macles.blogspot.com/2008/07/installing-firefox-3-on-acer-aspire-one.html)
So I can now use the Internet, openoffice, send instant massages and email.
But how can I get the pictures from my iphone, isnt that a normal usb camera driver? Shouldn it work out of the box? I installed picasa 3 beta for linux. Here I have two problems: picasa doesnt show up in the right click menu on the desktop, so I have to open one of those files in

Code:

/opt/google/picasa/3.0

but I dont know which.
Second problem is: picasa recognises, that there is a camera pluged in but it says that there are no pictures.

I'm still looking for a good twitter client.
And is there something like launch bar (mac os x)?
Do you now a good php, css, html - editor and something to sync with ftp servers?

Thanks for replying! And I'm sorry if some of those questions are already answered, I searched the whole internet for some of those questions, I'm fet up with searching

Cheers, and thanks again!
