Everything I've heard and all the advice I've been given is that if you don't need orgo, don't take it. The orgo on the MCAT is only semi related to the orgo you take anyway, so it really doesn't help you much. If you want to take orgo go for, but if it's just for the MCAT either don't bother OR I know a lot of people who took it in summer school the year before they wrote their MCAT.
As for English, if you think it'll help go for it. I personally find verbal reasoning the easiest section of the MCAT (I'm studying to write mine currently lol) and I never took English in uni ( though I did take English AP when I was in grade 12 (3 years ago) and I find VR to be almost exactly the same as the work I was doing in that). So if English is something you struggle with, then it would probably help. Keep in mind I've heard it's very difficult to do well in university English, so again if you're only taking it for the sake of the MCAT it might not be your best option.
I've also been told that you probably don't want to do too much else the summer you take the MCAT.
