Taper?

I am an unaffiliated masters swimmer who does 3-4 meets a year and self-trains at my local Y. Lately, I've only been doing about 1500, 3-4 times a week, but mostly race-paced training (something like 300 moderate warmup, 200 kick on back with fins, Main Set (all at about 85-90%): 3 100s, 6 50s, 12 25s, all at about 90-100%, 150-200 cool down. I have a meet Sunday. I swam yesterday. Last time I had a meet, I did 2700 the day before and was sore and all around pretty zonked and did crappy times. I am also 60 years old. Any recommendations for what I should be doing today and tomorrow (Fri/Sat) before the meet?
