It should be fine, without needing to reinstall Office. All documents will definitely be there, but it's always a good idea to backup your drive before doing anything significant, like upgrading the OS.I was wondering if I need to reinstall MS Office (2011) after Lion upgrade; I currently have it running under SL. According to Apple genius software and all documents should still be there (and working) after upgrade.

Mine continued to work fine after upgrading. I don't use Office that often though, because it's sluggish as all get out (on my machines, at least, YMMV).
Once I moved to the 13" MBA MS Office works quite well
I use it on both a 15" MBP and a Mac Pro, and it's sluggish on both. Although "sluggish" isn't a very quantifiable attribute, so it may just be I'm impatient.
Pages/Numbers opens/runs faster, so I use those, and only go back to Office if I need to for interoperability, but that's pretty rare, and usually only with spreadsheets.
^ MacDawg, is that an SSD Air though? Because office is great for me too (launching) from an SSD. The OP may not have an SSD.
