Printing fine, then next day feeder starts skipping/going backwards rapidly for half a second now and then
What you are referring to as the culprit is the white PTFE coupler, which indeed can start showing signs of wear. Looks like you found it!
It is hard to pinpoint an exact number of print hours on it, since it continuously receives pressure from the spring above it and what filaments you print (how hot your hot end gets) is also influential.
The fact that it is a consumable and can show signs of wear is a fact though.
With the Ultimaker 2+ we have replaced the spring by a spacer, and replaced the PTFE by a glassfilled PTFE, which is stronger than the 'old' one. If you still had the old one, a new one may last longer.
About error 2, why would you want to move the printhead so fast?
What probably happens, although with filament is seems unlikely unless you move it really really fast, is that you make the steppermotors turn, which generate some power which make it to your electronics. That may probably cause it to freeze.
Best remedy is.. don't move it too fast manually

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
