Port Forwarding & DDNS to connect home?

I'm running a Linksys WRT54G router with it's firewall turned off for this
testing. I have a WinXP SP2 computer at home and at work. I'd like to connect
to my computer at home from work. My ISP says they do not have a firewall up.
I disabled it at work and at home for this testing.

I've set up Port Forwarding on my router configuration interface to send all
traffic on TCP port 3389 to the private IP address of your home
computer. My router issues DHCP but I don't turn my computer off or reboot
the router at all...so it should change BUT I've read that it would be a good
idea to install and run a dynamic DNS service on your home computer.

First, I'm reading three IP Addresses. One from my home pc and the second
from the router in cmd > ipconfig /all and the third from my Linksys Config
website (ie, Status > Router > IP Address. Second, I've registered at
No-IP.com based on suggestion. For what, I don't know but I have a DNS(?)
address now that I believe is mimicking the router's IP Address? I am used to
VPN'ing into work from my home PC, then remoting into my office PC and
working from time to time. Can someone please advise me on how to connect
from my work PC into my home PC? Thanks in advance.

Your router should be the one with the public IP. It is the one forwarding
the port requests to port 3389 from the outside world to the internal
computer IP. It is the one that needs to have the Dynamic DNS setup on it
and maintained.

Don't forget - in order to use Remote Desktop on your home PC, not only must
the router be configured to properly forward the request on port 3389 to the
internal IP of the machine in question, but the Windows XP Firewall must be
configured to allow it, you must have a username with a password that is
allowed to connect to the system with Remote Desktop (Remote Desktop Users
group) and the Remote Desktop itself must be enabled.
 
I've performed all that you've suggest. Although, my router has a DDNS
option. I selected the DynDNS.org option and reestablished a hostname.

Now, do I setup a VPN connection (using DynDNS hostname; username/password)
at work then Remote Desktop into my home pc using it's computer name/IP
Address? I've had no success. What steps do I take now?

I know that I have to reset the router's password from admin to something
else. That's done. But now, how do I connect to my home pc from work?
