validation confusion

I use an editor that comes with HTML Tidy (updated version April 2000) & has
other validation tools for CSS & the WDG validator.
I validated my pages with HTML Tidy, & after correcting a few things, it
found no errors.  I had/have a DTD of HTML 4.0 transitional, but Tidy said
it validated as 4.01.

1. Do I need to change the DTD?

2. The WDG validator says that I may not use valign="bottom"..."bottom"
being not valid, but w3c's specs for both 4.0 & 4.01 list those attributes,
& I didn't see anything about them being deprecated...so what's the real
scoop on this?

3. (biggest problem) HTML Tidy didn't find anything wrong with my form
having a "name", but WDG did, & while the form works great, (at least for
its intended audience (browsers 4+) & effect supplied), WDG's validator also
insists I have to use an ACTION with it--if I do...which??
This form uses a dropdown box to call a js function that writes information
in a span below the box.
