The Shield you're lookng for:
the Shield you must find in Aleroth, andalor would help you there, you'll see
To go to Aleroth?
you must find minimum 3 different parts of a Zeppelin and give them to the man how stand nearby a Zeppelin in the Harbor (by "the docks" you mentioned)
For number 5:
Go to Hig Hall Village and the first man (is also a shopkeeper I think) you can met there can speak the language ;), sorry, forgot his name
The other things, honestly, I don't remember good enough to help you out!
Success!
