You sound frustrated, for which I am sorry. However, there are a ton of books on how to install and integrate Linux. SuSE, for example, comes with a manual if you buy a commercial version from Novell. There are also excellent sources of information from commercial publishers. And, of course, you can always rely on the Internet.
There is a learning curve with every new piece of software -- and this includes new versions of existing software. For example, I expect that the upcoming Microsoft Vista product will require getting used to. If you don't have time to devote to this learning process, I recommend using an outside service provider to get you going.
