Setting up a REAL VNC connection between 2 systems where each have a Linksys router

I live in a community where I have become the local "expert" on PCs.  I am hardly an expert but know enough to help folks in need.  What started as a neighborly gesture has become something quite time consuming.   Most of the problems are simple and if I could find a way to have the neighbor allow me to connect to their system, I could probably help them remotely.  I do this entirely on a volunteer basis and no fees are charged.

I have an XP Home system with a Linksys BEFSR41 wired router.  Most of my neighbors have a similar configuration although some are dialup and some have a Linksys wireless g router.   We all use the same ISP.  I've downloaded Real VNC and have read the documentation several times.  However, not being a network techie, I am not sure that there is a simple way for me to install VNC and its associated settings and router settings so that I can connect to it.  Is there a site that will take me through the setup process for both the client and the server?  I have also read a bit about TIGHTVNC.  Is this a preferred program?   It also appears that the only way to make VNC work is to set each of the systems up with a static IP address.  This is against the recommendations of the ISP.  If I do this, will I affect the connection to the ISP?   If in your work with VNC, you honestly think that I might be getting in over my head,  are there other freeware offerings available?   I also have some concern for opening my system and others to the potential of being hijacked.  However, I am assuming that once the VNC session is completed,  the open router ports will not allow anyone in but I am not clear on this point.   your help as always is appreciated.  

My apologies for asking some elementary questions but I really would like to find a simple solution that will save me some time.

You need to use a dynamic DNS service such as no-ip.com or dyndns.org (both free), and install a dynamic dns client on each computer. Then, you will need to forward the port ( I believe tcp 5900) for VNS inu the Linksys router (advanced > forwarding).
