Custom Task Form - Questions On Controls

I'm using O2003 and I created a new task form and had a few questions.

1. I added the DTPicker custom control for my date picker. When I
expand the calendar, it seems to always pick a date around 30 days in
the future. For example, I just clicked on it and it defaulted to
January 7, 2010. Is there a way to have it default to today's date at
5:00 AM?

2. Currently I am using the Notes and including attachments. Is there
another control I can use to also add attachments (in addition to the
notes control) as Outlook will only allow one Notes / Message box?

3. Is there a way to add a button to bring up the Category list?

Thanks.
