Doing a clean install- can I use Migration Assistant?

Hi all,

My 2008 white MacBook has become increasingly slower and slower over the past few months. Additionally, I also have tons of useless files and applications and I've decided to just scrap it all and only port over the things I need. So my question is, am I able to use Migration Assistant on freshly installed Lion to select and port over specific files (iPhoto library, Documents, etc.) from my Time Machine backup?

Thank you.
