Installation of bundled software failed on the MacBook Pro 10.6

You can re-download Lion even though it has already been installed by holding down the option key before clicking Purchased.

Do not release the key until after the option to Install appears alongside OS X Lion.

The workaround may be more reliable if something other than Purchased is in foreground before alt/option-clicking Purchased.

Burn the installer to disc, then delete it when you're done with it.

Well, here are a few things:

1) That OS X installation disk (10.6), will only install Snow Leopard for your 2009 MBP

You cannot use that disk for OS X installs on other machines

2) Generally, the applications disk is nearly useless. Your milage may vary, but I've never, ever used them.

3) Obviously your external drive (USB you say?) will have to have enough space to boot the installation process. I'd recommend 8+ GB if you will actually use this thing. However, you will only need a usb drive as large as the disk image file that we will create later on.

So, lets get started. There are probably guides out there that have more comprehensive answers than this, but I digress.

You need to use Disk Utility for the following steps. It should be in your Utilities folder. Put the OS X install disk into your Macbook, while your USB drive is also in the computer.

• Wipe your USB drive, and reformat it as Mac OS Journaled
• Create a disk image of the CD, saving it to your computer's hard drive.
• Once you have created the disk image, it should be on the left pane of the Disk Utility window. Click on it, then select the 'Restore' tab to the right. You will want the Source to be the disk image file (the OS X install disk), and the Target to be the USB drive.

Let me know how it goes!
