Get a cheap USB enclosure for your SSD and then make a bootable clone of your existing install on your SSD. After that, just swap the drive in. Carbon Copy Cloner should work for the clone.
This would be easier on you if you already have stuff on your new laptop, if you just want to reinstall Lion, there might be an easier way but I'm not aware of it.
I just finished reading the users manual. There is a section in the manual on boosting your performance by installing a SSD and then showing you how to install Lion through recovery mode. I assume there is a recovery mode thats not located in the hard drive but in a special partition outside the hard drive. I dont think Apple would leave us hanging there with no way to reinstall Lion.
You can ... You need to boot from an external disk first and then install Lion on the new internal SSD. Did that in the last days twice on an older MacMini.
The external disk you need to prepare once and could be reuse
you can also wait until Apple sell the USB sticks in the shop; wasn't there a rumor to have that end of August ? But you don't need, works without.
I read a KB-article from Apple on that be but can't find right the number.
Enter the following in google, it will help you: "install lion from usb site:apple.com"
I have a device that is similar to a usb enclosure. I plug one end into the power and through a converter, it delivers power to the blank/external hard drive and the other wire supplies data through the usb. It is very easy to simply clone your original Lion installation plus any apps or data you have put on. When it is finished, simply install the SSD and you will boot up and be ready to go.
