1).
Im looking at an example here:

SELECT P.PublisherCode, P.PublisherName, B.BookCode, B.BookTitle
FROM Publisher P LEFT INNER JOIN Book B
ON P.PublisherCode = B.PublisherCode

how this is different to:

SELECT P.PublisherCode, P.PublisherName, B.BookCode, B.BookTitle
FROM Publisher P, Book B
WHERE P.PublisherCode = B.PublisherCode


2).
Can someone explain to me the difference between INNER/OUTER and LEFT/RIGHT JOIN's

Thanks!

You can get a fair idea on INNER and OUTER Joins right here
