Drupal 7.x

First off: I'm faily new to Drupal, but i do know a fair bit about coding in php.

I'm making a website for a yearly LAN-party using Drupal and have run into a problem.
Beyond the users signing up on the site itself i need to make some kind of form where the users can sign up for the LAN-party itself.
When i started looking around for a module that might do this for me i stumbled across the Webform module.
I thought Cool, this is easy to use and i can create the signup without having to write a single line of code myself.
Soon after i was a bit disappointed, as i found out that it would not be as simple to show the submissions again. I know that the Webform module itself can show all the results, but i don't want all users on the site to be able to see the IP-adresses and such that the Webform module always shows.

Also the webform module can't pull values from the new fields module in D7, so i can't use new user-fields that i have made (eg. a users birthday or such) for pre-filling the webform.

So my question is:
Should i even be trying to achieve this using the webform module?

Maybe I just couldn't figure out what to search for (in which case, sorry for the dupe) but...

We are a group of Arab youth wants to use Drupal 7 to create a news and live coverage site to the revolutions in Libya and Yemen. What video modules (or ways) should we use in order to link the site to our cameras and provide a live video stream from the battle field (or the demonstration square) for our visitors? And if possible, how can we get the site to turn automatically to broadcast videos from the archive when our cameras, for a reason or another, stop working for some time?

I have node fields that I want to appear on more than one node at a time (similar to the way blocks work). I do not want to use views for this. How can I do this? It would be great if there was a php snippet I could use but I havent found one as of yet.

Instead of using Drupals default "Enable user pictures"

I would like to use my own field for the user picture "field_profile_picture"

How can I go about doing this? I've been looking at the following resources.
