Issues with Create your first world tutorial, part 2

Continuing on from Part 1 ( Issues with Create your first world tutorial, part 1 | Meta Community Forums - 1344833 ). 

I went through Part 2 of the tutorial, there are 3 blockers ( 2, 8 and 10 ).  These blockers could cause new users to get frustrated and not continue using the software.

Here's the doc listing them ( and other smaller issues ).

Hope this helps - I'll move on to the next tutorial docs tomorrow or Monday.
