Small Business Tools

I'm busy working IN my business and often find it difficult to find time to work ON my business. Any advice or ideas, please.

What resources are available for entrepreneurs whose company has failed? Are there books, websites, consultants, advisory/peer groups?

I don't see too many Posts - is this site active or useful or should one go elsewhere? Thanks

What can be done to make a web site more visible to the search engines?

I currently use Quickbooks in my business for day-to-day operations, but have an accountant that assists me with various things including taxes. I was curious if for a small business it would be advisable to use only Quickbooks for my taxes?...
