need two more blocks for news module

In the first block, all the news titles could scroll up from the bottom of the block continually.

In the second block, randomly select a fix number(which can be set by admin) of news titles to be displayed in this block, eg. set the number to 10, system will randomly select ten news from all news titles and display these ten news' title in this block each time user view page.

also, could anyone make admin(only admin) can change the color, font-size and the style of the news titles.

last, every news could be deleted(not just expired) automatically after a certain time which can be set by admin or user.

i thk this is not a hard work but i dont know how 2 do it
anyone could help? thanks very much
