Module development and code questions

I've browsed through the flickr modules, and they look good - haven't installed any yet, 1 - waiting for the final release on the Flick module, and 2 - not sure if that is the solution I am looking for.
Here is what I want to do:

I would like my users to be able to tag their photos in flickr with a specific name. I would like my main photo on the site, to rotate between, or maybe set it to change daily between all flickr photos with this specific tag.

Same thing with Youtube, but I'll do flickr first! Any suggestions?

Hi, I'm new to Drupal and I'm using Drupal 5 with the Event Module from http://drupal.org/node/103695.
When you view your events, you can click untill the event is show as a node with the body from node_revisions presented as well. The node page contains the event name as title, than some information on the posting date, an summerization of the taxonomy terms, start time, end time, timezone and finally the description of the event.

It looks like this:

Event title
Posted February 8th, 2007 by user
in taxonomy_term1 taxonomy_term2
Start: 18/02/2007 - 10:00
End: 24/02/2007 - 16:00
Timezone: Etc/GMT+1

Description of the event.

What I like to have is some additional fields to the event (like price, maximum number of participants, etc). Therefore I thaught to use taxonomy for this where price and maximum number of participants etc are taxonomy vocabularies. This way, when registering an event, the user has to fill in values (i.e. taxonomy terms) for these vocabularies and I'm able to capture the additional fields for the event. However when showing the event as a node (not in calendar), I would like to see a listing of the vocabularies and according taxonomies, like below:

Event title
Posted February 8th, 2007 by user
in taxonomy_term1 taxonomy_term2
Start: 18/02/2007 - 10:00
End: 24/02/2007 - 16:00
Timezone: Etc/GMT+1

Description of the event.

How do I select the number of pages within a taxonomy term, including pages in it's child terms?

What I actually have to do is harder. I have to make a list of all the child terms of a given term, and the number of pages within each of those children. For example:

I am using the category module and I am wanting to add a page that will let users submit recipes to a specific category. I want them to be able to type the title and recipe info then select the category it will go into. I already have the custom node asking them for the title and recipe info but i cannot figure out how to allow them to select the category it goes into. I am pulling my hair out and I know it has to be something very simple. If anyone has any suggestions please please please help with this. thanks.
