Moving to Lion, help with iWeb transition

Hi guys,

I'm getting a new mac, which will force me onto Lion, but I still want to be able to use iWeb. I host through an ftp server so Mobile me is not an issue I believe. Can anyone help tell me if any of the following is true/possible?

1. Through migration assistant, onto my new lion machine from my snow leopard one, can I transfer my apps to have a working iWeb on Lion?

2. I have both the Leopard install disk that came with my laptop, and the snow leopard one. Is iLife 09 (inc iWeb and iDVD) on them so I can reinstall onto Lion?

3. I have an additional copy of iWeb that Apple briefly put on their website for free as a dmg when they stopped iWeb. (Someone posted the link on here, but I can't find it now...) Will this install iWeb on Lion?

4. I have a firewire 800 clone of my snow leopard machine. If I plug this into my Lion machine, will it boot to my old system?

I'd really like to keep iWeb for just a little bit longer. I don't have time at the moment to migrate to wordpress or something but am imminently getting a new machine. Any help you can give me would be greatly appreciated!!!

Thanks very much!
