A good place to start is the FPC/Lazarus wiki: http://wiki.freepascal.org/

"Free Pascal documentation" is more about the compiler, what features it 
supports and the one or other help topic.

"Lazarus documentation" is about the Lazarus IDE and the LCL (the 
Lazarus Component Library). There you can find some overview topics of 
the IDE and the usage of the LCL and some specific help pages (just read 
them and may be you'll find something interesting).

Regarding your "shared files" problem, I'd suggest you to take a look at 
"Lazarus packages".

For many other problems (like using components, controls etc.) you can 
mostly(!) rely on Delphi tutorials and books as well (mostly Delphi 7 
and older). Some things won't work the way they work in Delphi though, 
cause of the fact that Lazarus is cross platform.

Documentation for the non-visual RTL and FCL (Free Component Library), 
which are part of every FPC distribution, can you find here: 
If you look into the %YourLazarusDir%\fpc\%FPCVersion%\packages 
directory you will also find many other packages that might be of 
interest for you.

The documentation of the LCL isn't as complete as the RTL and FCL one, 
but you can find how and from where to install it here: 
http://wiki.freepascal.org/Installing_Help_in_the_IDE (this includes the 
RTL and FCL help as well, but that doesn't hurt ;) )

If you have problems with the IDE or the LCL you can ask them in this 
list and if you have Pascal related problems or problems with the 
provided FCL you can ask them on the fpc-pascal list, which you can find 
here: http://lists.freepascal.org/mailman/listinfo/fpc-pascal/
