Welcome from a fellow PCLOS user (and member of Distro Hoppers Anonymous -- I backslid today and bought another pack of blank CD-Rs).
I thought I recognized your handle from the PCLOS Forums. Although I still consider PCLinuxOS to be my "home" distro, I've used Pardus for about six months and am very impressed with it. I think that it approaches PCLOS's level of polish and ease of use.
I hope you'll have fun using Pardus, too. The Worldforum here is not as large as PCLOS's, but it has friendly people who are willing to help -- and contrary to what you might have read, they do speak English (not just Turkish).
You might want to take a look at the Pardus Wiki, which offers good tips and how-to's:http://en.pardus-wiki.org/Main_Page
The package manager is called PiSi (which is also the Turkish word for 'kitty' or 'kitten'); it can be used via a GUI or the Konsole. The repos are steadily growing, and they even have the new version of KMyMoney and Skrooge. So I think you'll probably be able to find most of the applications you need.
