This is bi-weekly, not monthly pay.
Agree with terran - the taxes are what they are, if you're owing taxes when you file, then you're not having enough withheld through the year anyway - if you increase your exemptions, you'll owe more, and probably interest and / or penalties when you file next year.
My suggestion - increase the 401K contribution (you can go almost 10X higher than you are currently). While that will reduce your paycheck, the correct way to look at 401K contributions is as a part of take-home pay, so that's how you can do this. Put $400 / check more into 401K, save $100+/ check on taxes. The actual amount of your check will be less, but if you add the 401K to it, you've got more.
You could also find someone to marry, preferably someone who either makes a lot more or a lot less than you. The tax rates for single high-earners are pretty high, but not nearly as expensive as marrying the wrong person, so tread carefully here.
