I am doing the 200 fly for the first time. RUH OH!!!

It's gonna be next weekend on April 1 at the 2012 Pacific Masters SCY Champs in Moraga, CA. Please help me out! What do I do? What's the best strategy? My 100 fly PB is 1:04.2, but my in-season time is currently at 1:08.86. I will also be doing the 200 back and ***. I haven't done the 200 *** in ages. The last time I did it (Jan '11) was absolutely horrible- I got a 3:17 when my 100 time at the same meet was 1:29. My 100 time has since gone down to 1:17. I just really, really want to go under 3 minutes in the event. What do you guys think will help? As for the 200 back, my PB in that event is a 2:31.72 from a taper meet last July. My converted scy time from a meet close to that one is about a 2:47, but I'm getting down pretty close, in the 100 at least, to my taper time at this stroke. Last month, I went 1:09.6, which was just a second off my taper time of 1:08.6. All suggestions, strategies, condolences... are welcome! If I don't survive, James Thornton gets to have all my posts.
