I too was overwhelmed but this is one of the best user communities I have come across and you will never be without help if you need it.
With that being said, I have had my Fascinate since January and I love it. I too me two weeks until I decided to root it and then I learned more about the custom ROMS and kernels and such. I have tried many including the GB leak. I like the GB leak but it did not provide that much more than FroYo. The one big issue that is happening is that it winds up corrupting the SD card to the point it is rendered useless and no one has been able to get it back yet. So for that reason alone I went back to stock and I haven't even bothered to root yet and I am not going to at this point.
Reason being is that right now I am at about 18hr with 30% left and have most of my apps installed. Point being is that my phone is very stable being stock and there is no reason for me to be on anything else right now. Of course I will try another leak when it comes out.
One more thing.... I use Go Launcher Ex and it allows me to hide all the bloatware so I don't even see it. It has a lot of other benefits too but this is one I wanted to mention.
Hope this helps you out.
