You have a lot of good feedback to start with.
If you haven't already done so - I would start taking notes on each new subject your learning.
Also start a new page for each topic - so you can easily add to it and refer back to it later.
I even write down who the information comes from - this does make a difference when you get into more complex topics because of the way different people use different products.
In the end this will save you a lot of time...
Soooo - keep reading - keep posting questions you can't find answers to - try not to piss anyone off along the way ... "and you should do fine."
