Where should I get information?

I want to read and learn on basic topics which are important for my endeavor. I believe my best options are either by Internet articles or books..
If you nice people could recommand or direct me to which ones of these should I read, it will be great..
I would especialy like to find information in these subjects-
Mortages and finance
Taxing and financial planing
General building maintainence
Laws

If you have any ideas on other good subject I should know in you opinion then please share your thoughts.

Thanks
