Because this symlinks /data/app to the partition on your sdcard, anything that installs to /data/app (which is anything you get from the market, for instance) will be on the sdcard. The only way to force things onto internal storage is to install them to /system/app. I'm pretty sure the dialer and live wallpaper apps will be there by default. You'll have to move handcent to /system/app manually, either from the command line or with something like Root Explorer.
If you decide to move apps to /system/app, remember that you must first remount the /system partition read-write. You will also have to update them manually - updates will automatically install to /data/app.
