Just received 12" iBook G4 1GHz ... have downloaded and installed updates via Software Update but there are three showing in the update window which appear to be 'optional' (i.e. they didn't have a green button beside them and didn't install automatically like the other 9 packages).

The first of these three is Airport Software 3.4.1 with a grey info arrow next to it and an unchecked check box. The other two are Apple Bluetooth Module Firmware 1.1 and iSight Update 1.0.2 neither of which have a grey info arrow beside them, although they each have unchecked check boxes next to them.

Does the fact that these three didn't install like the rest, and require me to actively select them via the check boxes mean:

1. I don't need them on my machine?

2. They are optional on my machine and can be installed if I want?

3. Some other reason?

Any help would be appreciated.
