[wp-hackers] Plugin to update all posts in a category

I'm working on a plugin to update the custom fields of an entire
category of posts in one go.
For example, I have a category called photos to which I add all posts
that have photos. If I wanted to add a new tag to these posts (stored in
a custom field) then I'd go to my plugin page, select the category, and
choose the option, "add a tag to this category".
I'm having a few challenges that I'd appreciate any pointers on.
1) I'd like to list the categories as a drop down menu, so one can be
selected, with the category id as the value. I''m looking at the
wp_list_categories function, but I don't think that's what I want.
2) I want to get a list of all the post ids from a single category.
Again I'm looking at template tags, but I'm sure there must be a better way.
3) I plan to use a foreach loop to circle through each post and then use
the update_post_meta() function. Any feedback on this approach would be
The plugin will be under the GPL licence and I'll be happy to upload it
to wp-plugins.net and so on.
