Here are the solutions for people who just get this model. I spent more than 4 hours figuring out what I want.

[How to convert AVI to MOV using SMC]
Please follow the ways. Once you finish installing SMC, I suggest you that your computer need to restart.
Run SMC -> Hook up Sansa using USB cable (if you hook up Sansa first to your computer and run SMC, your computer won’t detect Sansa which means the option of “convert” on the top of SMC wouldn’t be available)
In my case, even though I followed the steps above and my Sansa was detected, my AVI movie files couldn’t be converted with an error message. I spent another hour to take the alternative to install Quick Time Converter. I don’t know why. What happended was when I rebooted my laptop and followed the same ways, I was able to convert any kinds of AVI files to MOV using SMC. Now I can enjoy what I want to watch using my Sansa. ^^ However, there is still one problem I need to take care of. Like the lagging problem, the audio runs a little faster than the video when watching a movie. Anybody knows why it happends?
[Transfer MP3 files to Sansa]
I heard that Windows Media Players or Windows explorer are availale to do that. I found another way which is to install “Media Monkey”. You can down load it on the website. Can anybody help me who to transfer MP3 files to Sansa using Windows explorer?
I hope this information I obtained yesterday would be of help for other people. You guys don’t need to waste the time!!
