Firebug page speed Questions

[webevelopersFTW]

i am getting a few messages from page speed that i am wondering if you guys could help me out with

this is after using minify

"The following cacheable resources have a short freshness lifetime. Specify an expiration at least one month in the future for the following resources:

* ?b=c/css&f=logindemo.css,loginslide.css
* ?b=c/js&f=jquery-1.3.2.min.js,slide1.js,va... "

these are my two

<link type="text/css" rel="stylesheet" href="min/?b=c/css&amp;f=logindemo.css,loginslide.css" />

  <script type="text/javascript" src="min/?b=c/js&amp;f=jquery-1.3.2.min.js,slide1.js,val1.js,log1.js"></script>

how do i fix this ?

i am also getting this

"The following resources are missing a cache expiration. Resources that do not specify an expiration may not be cached by browsers. Specify an expiration at least one month in the future for resources that should be cached, and an expiration in the past for resources that should not be cached:"

ok i know this is a stupid question but, what the hell. if i am on a hosted sever how do i gain access to the httpd.conf. i am familiar with apache's httpd.conf file via localhost but, hosting is very new to me.

Usually you don't have access to it, but you could ask your host to make changes.
Access to the .htaccess file is usually sufficient.
