Yes! You will be kicking yourself once you do it and see how much of a benefit there is, for the little amount of work it takes to do it.
And honestly the only reason I have the enthusiam to type these responses is because the whole process has been so rewarding for my phone personally.
Really the whole process is just more nerve racking then anything, and once you get done you will be surprised at how simple it is.
You can look these terms up in the forums, but I would suggest roolers guide or one of the guides that can be found by clicking back a the first few pages in this section.
But here is what you do. Ill sum it up, and you can look up specifics in the guide.

Make sure you are updated to android 2.3.340.
For first timers go with apex, it keeps all the blur you want and gives you the option to get rid of what you dont want.
Get bootstrapper, make a backup. (roolers guide has directions)
Now get titanium backup free, click menu button, batch, backup all apps and data.
Now make sure your contacts are synced with google.
Ok so you have a backup up everything now, including a save to go back to incase you somehow botch the rom install. (very rare)
So now you are free to rom as you please, always following directions. If anything happens you go into bootstrapper and load your save and pretend nothing happened

From everything I have read on here, and in my experiences. All the problems you see people encountering are from trying to update to a newer version of android instead of doing it OTA. I rarely ever see someone on 2.3.340 or whatever version have problems if they are installing a rom for their correct software version. Always make sure the rom is compatible with the system version you are using.
