Congratulations! Well, you certainly have plenty of time to get ready for the big day.
Swimming... keep at it. If it's your weak area, go 2-3 times a week. You have to come out of the water fresh, so you don't suffer on the bike and run.
For my preparation for a sprint, my coach had me swimming around 6,000 yards/meters a week. Now, for my preparation for an olympic distance, my coach has me swimming around 8,000 yards/meters a week. I think I'm swimming too much though!
Cycling... you want to make sure that you can ride the distance and come off the bike feeling fresh. For me, the key is making sure that my heart rate doesn't get too high on the bike. If it gets too high on the bike, my run is shot.
Running... you can run the distance... but can you run it after swimming and biking? For me, the key to feeling OK and not dragging across the finish line has been doing at least 1 brick a week. I typically ride 25-30 miles and then run 2-3 miles.
For my tri last weekend, I basically trained 5-7 days a week... and it showed. I was not dead at the finish line. Here is an example of how I trained for one month:
Bike: 13h 1m 37s - 197.07 Mi
Run: 9h 18m 40s - 51.95 Mi
Swim: 2h 40m - 9405.07 Yd
Spinning Class: 2h
Walking: 45m
Of course, I probably trained more than most do... you can get the job done without training as much as I did.
