What is the off beat quaver? Is the accent simply playing it slightly louder, or slightly longer, both or something completely different.
If you think of a pair of quavers, the first is on the beat e.g. 1, and the 2nd is off-beat the "and" when you count a bar 1 and 2 and 3 and 4. By accent I guess I mean slightly louder, although I think there's more to it that that - it isn't longer, the off-beat quaver is shorter and stronger. Say the word Be-Bop, with a longer first syllable and stress the "Bop" - that's kind of the feel. Or as others have said use Doo-bah, or Doo-dat

You mention playing the quavers legato but I have also seen notation with statcatos so now I am really confused.
I think this might be more of a way of trying to notate something that doesn't really fit into our conventional way of notating things. Sometimes you say the first quaver of a pair with a tenuto mark and the second with a staccato - that's sort of a way of showing that the first quaver is long, and the second is short and accented. You really, really need to go back to tip number 1 and listen. If you can't hear and feel this when you're listening you're not going to be able to play it.

In tip 3 you refer to stressing beats 2 and 4. How does this work? If I am playing a run in quavers how to a stress beats 2 and 4 do I stress both quavers that make the whole note for the 2nd beat or just one? If one which one?
Again, go back to tip number 1 and listen. Listen closely to the drums and you should hear a hi-hat click on beats 2 and 4. Try clapping, clicking your fingers, tapping your feet or whatever works for you on beats 2 and 4, you should be able to feel the swing. The stress is more subtle than the off-beat accents, but it is there.
Try listen to some classic big band recordings Duke Ellington, Count Basie - or something like Sinatra. Learning to swing isn't something you can do by studying the theory.
