You got a lot of overlap. You could sell one kit lens (the non-WR) or both since you have the 18-135, maybe sell one macro (the focal length you use less often) and I'm willing to bet you almost never use the 18-200 since you have the 18-135.

No? You probably refer to a 283 or 285, both are good flashes. Do you wish to shoot with a flash more often? Do you wish a manual flash for studio, a PTTL flash?

... but I'd be interested in opinions. How would you spend my allowance (ball park $1000) for me?
If your tripod is still good, get a good head to go with it instead of throwing it away. Your lineup is lacking in wide primes, but it's hard to decide for you what you will want to use.
It's hard to decide for you. My take would be to sell a bunch of lenses, get a fast 50, a wide prime (21 comes to mind) or if you enjoy zooms a higher-IQ zoom to complement your 18-135, maybe a 17-70 or 17-50 f2.8. Look at the end-of-line tripod heads from companies like Vanguard (great bang for your buck). As for a flash, it again depends on your needs but the cheapest all-around flash will be a Sigma 610 Super, so you could look at that one.
