How can I import blocks and stuff from sites to CAD2009

Hello....

I read the thread that's called : Good Sites for Free Materials

http://www.cadtutor.net/forum/showthread.php?t=25546

I checked them all but the problem is, i didn't know how to import the materials to walls and so many things, i couldn't apply them to my walls.

Also, i tried to import a tree, but i found out that it was TOO big, well huge and i didn't know how to make it smaller, i tried to scale it, but it takes to long to do so, and my pc is kind of old, a 5 yr old lol. so maybe that was the problem or is there any other way to change there size and fit them into my drawing... ??
