Mine does the idle thing for few minutes to. Could be exhaust or something knocking when going over a bump. I'm no guru but no one has replied so thought i'd try and assist.

My golf also does this on startup and if i remember rightly its actually trying to warm the engine slightly before use, if you let it idle for a while after a minute or so the revs will drop down to 800-1000. Im sure i was  told not all golf do this though.

As for 2 and 3 you could have a bush that needs replacing or something but hard to say with such little information, need to get under the front end and have a look. Check your cv boots as they may have split and lost all the grease.

I had a knock coming from the front left turned out to be a worn bush i thought the shock was broke.
Think a new wish bone is easier there about £30 new!
