Consider using the custom Google search labelled 'Search for how-to's and tutorials' when you need advice about doing something. It's available from the right-hand column.
Since it's a custom search it filters out a lot of stuff by favouring those sites that have higher concentrations of tutorials, examples, samples, lectures, and so on.
I've just added two more sites that help with 3-D modelling and graphics, amongst other things. Give it a spin.
