how to transfer ONE single application? migration assistant?

i've upgraded to leopard, but i lost my original tiger install dvd's with ilife on them. i cloned a copy of my tiger installation for the sole purpose of moving my apps over to leopard, but i got excited after installation and manually input all my settings and installed the programs fresh.

i realized, however, that now there's no way of me getting back my ilife without transferring ALL the applications from my tiger installation, which i'd rather not do to this software work of art i have amalgamated

so my question is... can migration assistant move a single application? i've never used it before (mac noob) and i went as far as the customization section, but as far as i can see without actually clicking "transfer" it only lets me choose applications as a category, which i take to mean moving over ALL the old apps.

if i move them, are they automatically installed? or just sitting there ready for me to put them in the right place. if i go through with it, will i have good results using cleanapp to get rid of everything but ilife? thanks in advance.

would that link be how i go about doing it? basically it says to start the old mac in target disk mode (can i mount a cloned tiger installation like this?) then to copy the following folders over:

\Home\Library\ApplicationName .... which im assuming is iLife
\Home\Library\ApplicationSupport\ApplicationName .... iLife again for me

\Home\Library\Preferences (if needed)

if that's all i need to copy, then i am amazed. it would be almost literally impossible to copy an intricate installed program like iLife from one PC to another in windows.
