Help Help with CM 10.1

So I got this phone from my brother with wi-fi only and it really is powerful. I don't have a MicroSD and I had a few questions. This is the guide I am going to use-->(http://androidforums.com/threads/cm10-1-4-2-2-huawei-fusion-2-u8665.742013/)
1. Do I need to root before I do this?
2. Can I use Side load to do this?
3. Do I need to do the 3gs fix if I don't have a plan?
4. Will it ever be possible to get Lollipop on this phone?
5.What is this ICS Baseband? Do I need it without a plan?
6. Will this fix some package Parsing errors I get?
Thanks in advance
