Is it worth reencoding with 240/24, or is it only a minor codec/bitrate efficiency issue? (i.e. is the 'rule of thumb' there to be an optimal setting for x264 in some way and how bad is deviating from the rule - just a trivial difference in encoding efficiency I am hoping!!)

If you reencode with a 240/24 gop lenght you will lose quality (if all other things remain equal). Basically longer gops help compression efficiancy, but at the same time they make it harder to seek the stream. The rule of thump is to simply use 10 seconds as the maximum lenght. In reality there probably won't be much difference between 240, 250 and 300 frame gops at the usual framerates.
