The Cobras are great. The Bridgestone Exedra Max is also a fantastic rear tire at almost half the cost.
If you remove your rear wheel yourself, 2 Wheel Performance in Elkridge will take off your old tire, and mount and balance your new tire for $50. The front will likely be cheaper.

Since you're replacing your tires, you might as well upgrade your brake pads to EBC. You'll want the FA236HH (2 pairs) up front and the FA209/2HH (1 pair) in the rear. Don't forget a thin smear of copper grease on the back of the pads and on the pins.
Since you're changing your pads (and likely brake fluid), you might as well upgrade your brake lines to braided stainless steel. I noticed a significantly stiffer response.

Since you're flushing your coolant, you might as well upgrade the old leak-prone hoses from rubber to silicon (see my failure thread here:
Blew a coolant line). Don't forget to buy the associated stainless steel clamps.

I really like Motul 7100 4T 10W40 oil for this motor.
That should get you started on a long and loving relationship with your new ride.
