apps on other partitions?

[Lotas Smartman]

Hello. i just bought a new hard drive for my imac, an 80gb model. i 
setup 2 partitions, like i was told i had to (a partition less then 8gb 
and then an other with the rest). so, i did so, but theres a little 
problem. the partition with 8gb is running out of space, and i have 
only installed OSX, and some of iLife 04. when i try and install stuff 
like xcode or the rest of ilife, it tells me i have to put it on the 
boot drive, and the other drive has the red exclimation mark. anyway, i 
have moved my home dir over to the boot drive, but any ideas what i 
have to do to get the apps over? would it be as simple (or complicated, 
depending on how you look at it) as just moving all the apps over, 
making a symbolic link and its done? or even copying all the apps over, 
testing the symbolic link, and then removing the old apps? could that 
work?
Thanks in advance for info!
