Can’t Seperate Pages W/O Messy Solution

Hi I have a question regarding seperating pages in Word Press. Basically my setup is like this:

– First page shows 1 news item only
– Category pages shows 5 news items and I want it to show Previous/Next links for those older news items.

I got it working with this:

<?php //Shows Next and Previous on All-News page
if ($cat == 6 | $cat == 11)
{next_posts_link(‘<p class=”left”>« Previous Entries</p>’);
previous_posts_link(‘<p class=”right”>Next Entries »</p>’);
echo (‘<div class=”fix”></div>’);}
?>

However, with that solution I have to add the individual categories like 6 and 11 for the Previous/Next buttons to show up.

I’m thinking that a better solution would be if there was a way I could call it so “IF NOT IS_HOME() THEN SHOW NEXT/PREVIOUS links”

Can anyone help me do that? I’m still learning PHP so these if/else statements with the wordpress jargon is difficult for me.

Thanks!
