You can delete all traces of JBPatch in the userstore, since JBPatch isn't installed. No need to find an uninstaller, the firmware update already did that.
jailbreak(-log).sdr is just the annotations folder for the ebook that was created to notify you of the successful jailbreak. (I thought that was a feature of yifanlu's JB, this JB didn't do that though???)
the "rp" folder can be used for auto-recovery of the Rescue Pack in certain edge cases. (it should have the Rescue Pack files in it, though...)
