I decided I would try out newtor suggestion for you and install openoffice from linuxpackages.net.
It worked flawlessly on my freshly installed VL Gold. After download, just right click on the package, choose install package, enter your password and away you go.
It even installed the icons in the menu, something our own version in gslapt would not do for me.
As far as tight VNC goes the closest thing I could find for an easy install is this.ftp://220.127.116.11/.1/vectorlinux/veclinux-5.8/extra/net/tightvnc-1.3.8-i586-4vl58.tlz
It is from the 5.8 repositories. I also ran it on my system. It installed fine, removed the other VNC software (x11vnc) like it should and I can launch VNCviewer from under networks in the menu.
I am not a user of tightvnc so I can not test it beyond that.
P.S. These packages are both removable the same way you put them in, by right clicking and choosing remove package. However, removing a package will not reinstall anything that was taken out when you put the package in. Example x11vnc.
