Two Questions regarding Menu System

Hi,

i have two question regarding the Default Drupal Menu System.

1.

I have one Page lets call it "node/12".
And two url aliases to that page "/alias1" and "/alias2".

I can access the Page by going to node/12, alias1 or alias2 and can see always the same page.

I also have 2 Menues. And want link in one menu to /alias1 and in the other to /alias2.
The reason is that the menu entries are on the second or third menu level on different first levels and i will perserve the menu strukture but displaying the same content in two different "sites"

After inserting alias1 as url for the manually added menu entry and reopening it instead of the url alias i see node/12 which links if i display the menu to the first url alias available for that node.

So is it possible to have one node, with two different url aliases, in two different menues, and in each menu the link to a different urlalias? or is there a clean way to display the node in that manner? (i can use views to display the same node but wtf :D).

2.

More a theming issue but, also related to the menu. I using the default Menu Blocks and the "Menu Block" Module in different Regions inside the theme to display my menues.
I use css to style the menu's and it works great. So now my problem is, that i want some (not all) entries of the menu in a different color than the rest of the menu. Is there a correct, or usual way to do so? I prefer a way that the user could set that menuentrie foo and bar are "red" instead of the default "blue".

Thanks for you help.

Phil
