Post installation

I'm trying to do something similar to this PHP snippet: http://drupal.org/node/63422 - except I'd like to select based on a custom profile field instead of a role. Any tips on this?

Is there a simple way to manage the file size of images before they are uploaded?
My users don't know how to do this, so they try to upload images that are much too big.
I'm currently using Image, img_assist and tinyMCE modules.
I've looked at G2 with Gallery, but it seems to be a very heavy duty application with much more functionality is needed for this.

I'm attempting to add my SIP URI to my contact page via the contact module's "Additional Information" field at administer >> contact form >> settings, which would appear to accept unfiltered HTML. See an example of what I'm going for.

So my users like to have long user names (not long like "supersuperlonglongname" where there are no spaces, but instead "super super long long name," with spaces. In most instances, like comments, and blog posts, their names are being truncated to just 14 characters, so instead their name is coming up as "super super lo..." How can I make it so that their entire name displays instead of the cuttoff version?

I'd like to remove the "subject:" field for posting new drupal comments. It's an optional field, but it displays the truncated body if it is left blank. I just don't have any need to display a subject for comments. Thanks.

In my filtered html I have:

Linebreak converter - 1
Inline Images - 2
HTML Filter - 3

And in my filter I have it set to strip disallowed tags.

My allowed tags are:
