is it possible to do the same with my blogroll list and will people on it still receive a trackback when I write something new
Yes and yes. I have created various page templates for the theme I'm using including 3 different blogrolls.
You should understand the difference between trackbacks and pingbacks though.
Trackback: You've just read something on another blog that inspired you to write your own post about. You write the post and manually send a trackback to the blog where you read the post that inspired you.
Pingback: You've just read something on another blog that inspired you to write your own post about. You write the post and link to the blog where you read the post that inspired you. WordPress will automatically send a pingback to that blog.
Both methods use different protocols.
Also, I wonder how you do link to the page you created... I mean: do you manually add the link in the sidebar and the menu?
You can add it manually if you want to but if you're using the wp_list_pages() tag the page will be printed out along with any others.
