Even if you have a pirate copy you should install SP2, it has heaps more security fixes and other such improvements.
If you are using a fake copy of windows just don't do windows updates after SP2 or it will catch you.
I ordered SP2 as well, this was when it came out and dial up was common so 100mb was BS to download.
You won't have a problem isntalling off the CD i've done it numerous times. If you have 2 hard drives and the second one is bigger I suggest unhooking it. When I did my PC my 2nd HDD was bigger and windows puts its temp files on the larger drive, it then couldn't find them (even when I told it where to look) and broke the installation...had to format.
Also uninstallion of SP2 is NOT a good idea. The system rolls back but I'm sure you'll find many things break and you'll end up formatting. I've never seen it go back happily.
