No you can leave your apps alone and there is no need to worry. You can easily tell what apps are 64 bit by going to Activity Monitor (Applications-Utilities-Utility Monitor) and it will show in the column labeled Kind.
There is much confusion about the 32 / 54 bit applications. At this writing there are VERY few applications that are 64 bit and Snow Leopard boots in 32 bit. Even if you force booted in 64 bit you would NOT see any performance increase.
