[OpenLayers-Dev] Game development problem - speed with lot of

I´m gonna explain the hole problem.
I want to do some browser-game using openlayers, similar to the-west.net
game. I have already seen just one (warwide.com) using openlayers (but they
are using markers).
Game map should contain some objects as houses, rocks, players etc. Some of
them are active (clickable) and some of them are just images (eg rocks).
I want to have these all objectives in mysql database and somehow load it
If understand it well, then for each of active object I need:
1) Image layer or something like layer that display raster images
2) Vector layer that defines clickable area of that object (because it is
not always the same)
>From above should be clear, that I dont want to use markers, because
a) they are represented by icon, which is whole clikable or not
b) they dont resize on zoom, so eg the rock on zoomout/in wil be the same
size as before
I know, that I´m maybe little slow with thinking about that all, becaouse I
dont understand some yours explanations.
1) Is there any possibility to load these objectives from mysql with php and
put them into map with no slow loading (and them browse the map smoothly)?
Or is the only possibility to do that with some mapserver?
2) If the only possibility of speed this up is to make it with mapserver -
then I really dont understand how to do it. I must install some aplication
or service on the server? Because if my web pages are hosted on some server,
then I cant do something like that..
My code is now on http://game.argo.in/game.php http://game.argo.in/game.php
As you can see from source code, all objectives are loaded from mysql by php
Loading and browsing is slow. You see also that there are layers with images
and layer with clickable polygons. I know my code is not ideal, so I want
somehow to improve it to have as quick as possible..
Thanks for any advice..
