Expression Engine auto_path

Hello I'm very new to EE and am having 2 issues.

I'm using [code]<a href="{auto_path}">{title}</a>[/code] on my custom search results page, however, instead of linking to "http://www.mysite.com/This-Is-My-Page" it's linking to "http://www.mysite.com/index.php/This_Is_My_Page"

I think the index.php has to do with the search results page being "http://www.mysite.com/index.php/results" In my search form I have:

[code]{exp:search:simple_form weblog="weblog" no_result_page="noresults" result_page="/results/" search_in="everywhere"}
<label for="keywords"></label><h4>SEARCH My Site</h4>
&lt;input maxlength="190" size="18" value="" id="keywords" name="keywords" style="width: 160px;" type="text"&gt;
<p>&lt;input value="submit" class="form_btn" src="files/send-button.gif" type="image"&gt;&lt;/p>
{/exp:search:simple_form}
[/code]

And the rest of my site doesn't use index.php in the url. So if I'm at "http://www.mysite.com/A-Page" and use the above search form I am taken to "http://www.mysite.com/index.php/results/STRING" I believe if the search form pointed to "http://www.mysite.com/results/STRING" Then the {auto_path} would not include index.php

My second issue is {auto_path} is using underscores not dashes for the links (i.e.  This_Is_My_Page not the actual page This-Is-My-Page).

So 2 questions:
1) How do I point my search form to "http://www.mysite.com/results" not "http://www.mysite.com/index.php/results" ? I think if I did this it would remove index.php from {auto_path{ in my search results.
2) How do I get my search result links to point to the correct page "http://www.mysite.com/This-Is-My-Page" not "http://www.mysite.com/index.php/This_Is_My_Page" I guess if I could solve question #2 I would be solving #1 too.

Thanks
