Resources for learning LINQ and Entity Framework Queries?

everyone. I'm trying to learn how to write LINQ queries, and am wondering if you can help me kick-start it with some resource recommendations.

I am trying to learn how to write simple and complex queries that look like this, which I think is standard LINQ syntax ...

from b in blahCollection
join f in fooCollection
where b.Field == someValue
select new { b.Field, f.field }

... and this, though I'm not sure what this syntax is called. (What is it called?)

var plan = blahCollection.Find(b => b.Field == someValue).FirstOrDefault();

The best resources, I think, would be those that would allow me to practice queries on sample databases. I've heard about LINQPad, but have not yet evaluated it. Is this a good choice? Are there better choices?
