It seems people always suggest a different crit value to stick with when it comes to the second haste breakpoint.
I've heard as low as 5k and that 11k that was suggested is the highest I've heard thus far.
Taking the second haste breakpoint would look something like this:

That would leave you with 8.7k crit, which in my opinion should be fine and only get better with more gear.
I noticed that your belt is quite awful, being 496 with only a single secondary stat. I would try to get at least a 496 belt with 2 secondary stats, since it would get you some extra stats to play with. If you can afford it, the leatherworking belt would be a very nice upgrade. With it you'd get 9.6k crit with the second haste breakpoint.

I would probably go for the second breakpoint if I were in your boots, but that's just my opinion and I'm no expert. You might want to wait for another opinion.
