Utter Noob...Help

[StayingPower]

Hi guys, SH3 has just arrived but I have absolutely no clue what I'm doing (did everyone's game not come with a manual or was I just lucky?).

I hope you'll forgive the noobish questions:

1)Don't laugh, but I'm having trouble with the tutorials. On the Navigation one, I set a course of SSE and completed the first objective, but I couldn't complete any more. I kept going SSE until I reached a German Destroyer before giving up.

2)Then I moved on to the torpedo tutorial, where i had some sucess. I hit a merchant with my first torpedo, but as I was admiring the explosion I forgot to order my sub to stop, and I went speeding by. I tried plotting a new course to get behind the merchant but for some reason my crew decided to approach it backwards. Is there an easier way to move and turn the sub without messing with dials and plotting (read: can I use the arrow keys or something?).

3)Is there a way to lock the camera on to the sub in external view?

I had no idea the game would be this hard, so please forgive the noob questions. I'm sure I'll have loads more once I actually get into the game.
