I don't use any post processing in-camera, only know it's there. So I can't answer [2] or [4].
[1] You can add focus adjustments for up to 20 different lenses. But for lenses the camera doesn't recognize (like manual ones) you can only add one global adjustment. I haven't used this option yet, though.
[3] I found continuous shooting pretty good but, as mentioned, I only have a rather old camera for comparison and never measured it. But that question was answered in a recent article about the different shooting modes:

Just the bit that talk about speed, where you get 3 to pick from. It all depends on the type of memory card you use:
Quote: High
This mode fires the shutter at 8.3 frames per second (fps). With a 95 mps card, expect about 4.3 seconds worth of images before buffer overrun. With a 45 mps card, expect about 2.5 seconds.
...
Medium
Medium works in the same manner as high speed but at a lower (around five fps) frame rate. This increases the amount of buffer time you have. With a 95 mps card, expect upwards of 20 seconds before the write speed slows. With a 45 mps card, around 10-12 seconds.
...
Low
Low works, again, like high and medium frame rates but at around three fps. With a 95 mps card, expect to shoot continuously until the memory card is full. With a 45 mps card, expect at least 30 seconds of continuous shooting.
Hmm, it doesn't specifically say if that's for RAW images.
Hope this helps.
/edit: I just checked, you can crop images with the camera post processing options. Still don't know how well it does any other adjustments or if you can store presets.

Off topic, but going by your name you might enjoy this.
I live in Munich, Germany and my colleague is absolutely in love and addicted to surfing. Even took his whole family to Hawaii once and it must have been a wondrous experience!
Lucky for him we have a river wave right in the middle of downtown (at the "Eisbach - ice stream") and a tamer one not far away. If you never heard of it, here's a trailer of a documentary about it (German, sorry):
Very different than being on the ocean, of course, but the water does pack quite a punch and I heard it schooled a few pros, too.
