These are pretty big projects! I have never had a project in Quanta this big.
I tend to have many sub-projects, and have never created a quanta project for 
our whole application tree. It does cause me some problems, because my 
libraries are outside my project directory, and not referenced - so 
auto-complete on my class libraries is a bit limited (Hopefully Quanta 4 will 
be nicer at this - but not really an issue at the moment).

Sounds like everything is current versions... pretty much what I run at home.  
At work Kubuntu is 7.10, and KDE 3.5.9.
Quanta 3.5.9 will not use anything from KDE 4, it will load 3.5.9 libraries 
when it needs them, just like any kde3.x app will.

Not sure about symlinks...

Under the project settings ( Project->Project Properties) you should be able 
to use the Exclude from Project option:
I sometimes use *.jpg;*.jpeg;*.gif;.*.backup.*
(a customer used to use file.name.backup.N as the backup version of the file 
where N is the version - nasty method from a previous developer, but I dont 
want to see those file)
You could try adding directoryToIgnore/*;bobsfile*; etc to reduce the load (do 
symlinked files have a common prefix or suffix?

This might be a good option for large projects, but I think development is 
concentrating on version 4, which is a total re-write and uses the kdevelop 
platform as a base.  Hopefully this will help to solve your problem as I 
would imagine more users of kdevelop would have larger projects.  I could be 
wrong here.... :-)

The above options are probably not the best in all cases, but hopefully the 
are a workable work-around for you.
