Replying to Just got a T1i! Help!

I got my T1i and a new lens for Christmas! I'm looking to get an extra battery and maybe some higher end fast shooting memory cards. What do you recommend? Also what's a good camera bag that has enough space for my camera, my wide lens, my zoom lens, and a few accessories like extra battery, mem cards, etc. Also one that is water/weather proof and can fit in my ski pack? Thanks Don't hate on me with searchbar. From the looks of these threads you guys like helping us DSLR noobs out. Thank you very much if you can help me.
