(many questions along dt line) pls help!

Just enter one of the domains. Make sure it is a running site with content. The website will then be reviewed by someone from Google Adsense. Once you have been accepted to the adsense network you will receive an email and you can now add the adsense code to any of your sites without need for validation. But they must stick to Adsense terms and conditions.

when registering, just enter one of your site that is active and content rich.
So, from that same account, you will generate code and paste on any of your site.

u can paste the code on as a many site as u want.

But when generating u should choose colors that blend with the webpage.

You can use "channels" to monitor revenue from each website. During the creation of the advert, you will get to a point where you have to "Choose Ad channels".

Basically "Ad Channels" allow you categorise your adverts so you can monitor each advert board's performance. It can be on the same site or on several sites. The channels themselves are just descriptive terms with which you can use to identify which is which among your adverts.

Example. I always name my channels like this. sitename.advert-type.

You said you have two sites: Site1 and Site2. if you wanted to create a 728x90 Leaderboard on each site, you should create 2 of these but create a channel for each. This will allow you monitoir, during reporting, the performace of each site.

The above sounds a bit tech. Let me know if you need more help.
