Welcome to Techsurvivors, Alex! I think you're our first Romanian member.
(Yes, I did the checks when you joined - we check out every new member because like most forums these days, we get a lot of spammers trying to sign up. And nice web site, BTW!)
Alex, sorry to be the bearer of bad news, but Apple (for some unknown reason) has not seen fit to provide that ability.

2.3 I have the html files of my website same as I see them when visiting my page on the internet with a browser. Is there any way I can get my webpage back to iWeb?
iWeb can't "import" html files.
If you don’t have the above mentioned domain file anymore and did not make a Backup of it but the website is still online (on MobileMe or any other server) then that’s what you should do:
1. You have to rebuild the website from scratch in iWeb re-creating each page
2. Use the published version on the server to copy&paste the content from it so you don’t have to re-type it in all over again. This makes the process of rebuilding the site from scratch really fast.
3. You shouldn’t do that by selecting all and then paste it into iWeb, it’s gonna be a mess. The best way to do it is text field by text field.
4. Images go by Drag&Drop. However the images on the published version aren’t full-resolution images. So if you still have the original image (full resolution) you better use this one. Especially if someday you want to increase the size of the image you will see that the one you took by Drag&Drop from the published site is poor quality.
5. Take advantage of the situation to re-organize your website and re-elaborate/modify it.
I'm sorry there is no better answer... But at least you don't have to type the text of your webpage all over again... And it's quite quick to do copy&paste (Believe me! I once did it for 300 pages!).
Apparently it's a much-asked question on the iWeb forums. I think your best bet would be to use your not-quite-up-to-date backups and copy and paste whatever updated text etc. that you need from the existing sites online.
While I certainly like iWeb's output, I've never used it to create a real web site because of various issues; its site structure, lack of ability to hand-edit code and things like this which are just basic, IMHO. I use Dreamweaver and other tools and yes, they have a much bigger learning curve and a lot more power. I've been building web sites for clients for about 7 years now and I'm still learning new stuff. However, I also understand that some people aren't interested in learning the nuts and bolts of web creation and just want to get a web site out there. For that, iWeb is great, as long as you are keenly aware of where it falls short. In the "closing the barn door after the horse has escaped" advice department, I'd recommend making a backup of your site every time you change it.
