404.php Over-riding .htaccess

Hi,

I upgraded our site (http://kellyswanson.net) from a custom Coldfusion site, to a WordPress site. I'm using Genesis 2.0.1, Streamline Child Theme 2.0.1, and WordPress 3.6.1.

I entered a bunch of 301 rewrites in the .htaccess file, but most of them are not working. I called my webhost about the issue, and the level 2 tech I spoke with said that the 404.php page (public_html/wp-content/themes/genesis/404.php) was overriding the .htaccess page.

Here's the related code (as far as I can tell) from the .htaccess file - there is more code in the .htaccess file from the W3TC plugin. Please let me know if you need to see the whole file.

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

Redirect 301 /index.cfm/hurl/idsPageID=1/Funny-Motivational-Speaker-Kelly-Swanson-Home-Page http://kellyswanson.net
Redirect 301 /index.cfm http://kellyswanson.net
Redirect 301 /index.cfm/hurl/idsPageID=4/Type=0/Kelly-Swanson-Calendar-of-Events-Open-to-the-Public http://kellyswanson.net
Redirect 301 /index.cfm/hurl/idsPageID=16/Type=2/Clear_Skin_3.swf http://kellyswanson.net/seehear/motivational-speaker-videos/
Redirect 301 /index.cfm/hurl/idsPageID=290/Type=/Comedy-Writing http://kellyswanson.net/comedian/
Redirect 301 /index.cfm/hurl/idsPageID=50/Church-Programs http://kellyswanson.net

I took out all of the redirects that I originally entered in the .htaccess file and I entered the ones above to try and troubleshoot the issue. The first two redirect work, the rest go to a 404 page.

I've also tried the 301 Simple Redirects plugin, but it doesn't see to make any difference.

I've been struggling with this most of the day, and I'd appreciate any help.

Best regards,
Bill
