Yoowza!

I thought I was slowly getting the hang of all this amateur photography but I feel completely lost!

There are a lot of very helpful people in this forum, many of them Nikon shooters and quite a few with a D3100, I've noticed. If you give more specific details of what you want help with, I bet you'll get quite a few replies.

A bit more than 'I'm lost' would help.

We still don't know what the problem is or how we can help. Post some pictures ask questions

Guess a sat nav wont help?

Post what you need help with and we will help.
My website has several videos dedicated to the D3100, but thats more controls and settings rather than photographic principles. Might still help you though.
