How to add exceprts but in this way

hello.
firstly look at: http://sti.net.pl/~killer/fano/index3.php
i’m already thinking about how to add (as you can see) few things on my site.

first of all i want to have two exceprts on the left side of site (aktualnosci) of latest 2 added posts. i know how to add excerpts but i dont know how to add them on my front page (in the number of 2).

secondly, i want to have a few titles on the left side, under ‘aktualnosci’ (pozostale wiadomosci), and a few just in the right bottom corner of site (wiadomosci).

finally i want to have a few excerpts of static pages on the right.

thanks for any replies.

the next question is: what if the function which returns adress of page user is already on?
