Apache Access

How would I allow Apache to be accessed from outside my network? I've heard its difficult, but my source is.... not reliable. I know it can be done, so how would you do it?

If you mean an internal network where you use internal ip addresses such as 192.168.1.1 or whatever then you need to look into Dynamic Dns to point yourdomain.com to the ip that your isp provides to your connection.

Take a look at http://dyndns.org

Then setup portforwarding to forward all requests on say port 80 to the internal ip address of the machine with apache running. Portforwarding can be done usually on a router.

what would you say if they give you a dynamic IP?

That is what you need to use Dynamic Dns, Dynamic dns will update the relevant IP details on a 3rdparty service everytime your IP address changes. Thus making it like you have a static IP.
