Tips for filming a wedding?

I am filming my sister's wedding and I want to make it the best possible with what I have.

My camcorder is a Sony Hi8 Handycam Vision CCD-TRV58. I am going to try to get the best out of it. I am thinking of using...

Avermedia MEZUSBGDR DVD EZMaker USB Gold Video Capture with an S video Cable.

I can not connect a mic to my camcorder. The sound quality is ok but I was thinking of getting a digital voice recorder and put it in some flowers next to the paster. Then I would upload it to my computer and edit it to the video.

Any more ideas?

Thanks

Just don't talk about the groom behide his back when your filming it... >_<

you could go around to everyone who comes to the wedding and ask them to say something nice about the bride/ husband/ couple
other than that
make sure you get lots of footage of the marrige, close ups for the really important bits, and experiment with differnt shots and angles maybe
