SBS 2008 DNS  records for self-hosting

I just installed SBS 2008.  I want to self host Exchange and a SharePoint site (not just the Companyweb default), but I cannot locate my site with my domain name from a browser and I can receive, but not send email.  I think this is due to my ignorance of DNS.

Background:
1. Domain name: example.com
2. SBS Server name:  server
3. Registered ns1: example.com 24.234.xxx.x1
4. Registered ns2: example.com 24.234.xxx.x2
5. Router IP: 192.168.x.x

Questions:
1. In the Forward Lookup Zones, should I only have records for example.local and remote.example.com, but NOT example.com (I am ignoring _msdcs)?  In simple language, does remote.example.com really mean www.example.com, so that example.com is not needed in the zone?

2. Should the example.local have NS of server.example.local and A record of  192.168.x.x?  Default install gave it these setting and I think they are correct.

3. Should the remote.example.com have NS of example.com and A record of 24.234.xxx.x1 (which is the registered ns1)?  
Default install gave it NS of server.example.local and A record of 192.168.x.x.

If you are wanting to self-host a website that is viewable from the Internet then you will need your Authoritive DNS server to point to your server, and you will probably need a NAT, Network Address Translation to map a public, routable IP address to your website IP address of 192.168.xxx.yyy.

Regarding email, what email client?  MS Outlook should "just work".  If you are using POP/SMTP then you will need to enable those features in Exchange.  Then they should work by specifying your exchange server as the POP (retrieve) and SMTP (send) server settings.

Thanks Olevi, I warned you about my ignorance, so a couple other questions:
1. Cox is my ISP.  I use their ns1 and ns2 ip addresses.  Does that make them my Authoritative Name Server?  Would they do the pointing to my server?
2. Would Cox set up the NAT or do I have to do it in my router or both?
3. How does your answer change my original questions above?  Are they still valid questions that I need to have answered?
From your question about email, I think the email issue is a separate one.   I'll leave it until after I get dns settled.  The errors I get are Not Allowed to Relay and they bounce back.

Authorative DNS:
Your authorative DNS could be Cox. I am assuming you have a domain name on the internet, yes?  Did Cox help you set it up, or perhaps GoDaddy or someone like that?  Wherever you got your domain name from, they are probably the place to go to add a record to point to your website.

NAT:
That's probably you, it is certainly in your firewall/router where you will configure it.

The NAT and the DNS entry will work together to get a path from the Internet to your server.  You will create a DNS entry, probably "www" that points to your public IP address.  You configure a NAT that allows inbound traffic on port 80, the http port, of your public IP address.  (Think of an IP address as the street address of an apartment complex, and the port number as a particular apartment within the complex).

That may not be enough information yet, but I hope it will lead you to the next questions?

As stated by olevi, the anser gets me unstuck, so that I can go to the next steps (questions).
