Layout problems with XHTML MP and WML

Things that have so far been a pain in the butt to fix:

1) A link like this blew up the DTD i was using :
<a href="wap_page.php?value1=blah&value2=blah">Link</a>

Q)Why did it blow up?
A)The "&" was the problem using This site I have to change "&" to "& #38;"

2) Field input, using this example I still cannot get the text and input fields to display like they have it (everything in line)

I cannot put the input fields into a table, as that blows up the DTD. And using extra spaces " " just doesn't do the trick, as 3 blank spaces might be displayed differently on different phone.

Example I want:

Login :   [_____]
Password: [_____]

This is what i get:
Login : [_____]
Password: [_____]

This could easily be fixed if in wml I could use "<pre>" tags, but I guess that will have to do.

3) This has got me stumped, i have cut out most of the code, but just show how fun this is here is the simple version :

<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.3//EN" "http://www.wapforum.org/DTD/wml13.dtd">
<wml>
  <card id='input1' title='Wap Page'>
    <p>
      <anchor>
        <go href='wap_page.php' method='post'>
          <postfield name='report' value='yes'/>
          <postfield name='type' value='stuff'/>
        </go>
        Display Details
      </anchor>
    </p>
  </card>
</wml>

Now what is the problem? Well the anchor link works on Telstra using my Nokia 7250i, but when I change sim card to Vodafone on the exact same phone, the anchor link doesn't work. It just points to the top of the page. I really couldn't be bothered chasing this one up. So I used a different type of link...
