I do not believe that you are rooted. Looks like you have pure stock Eclair out of the box with Rogers.
And here's a little info for ya...
In the days of Eclair and Froyo, rooting ur phone was needed initially in order to get the ClockWorkMod Recovery (CWM) on ur phone. And from there once you had copied an Eclair or Froyo Rom to the internal sdcard of the phone, you could use the CWM to flash (install) the Rom that the Developer had made.
Later, once the Devs started baking (building in) the CWM into the kernels that were included in their Roms, it was realized that if you just used Odin to flash that dev kernel to ur phone you could then just reboot into the CWM and from there flash the dev's Rom. So in fact, you do not have to be rooted to install a custom dev rom. But you need to be familiar with the use of Odin and CWM Recovery.
And as far as the Gingerbread Roms, well... that is a different story- kinda.
Your best bet, as you have stated that you have read a lot, is to read and read some more. And you could also go to mobiletechvideos.com on youtube -- there are excellent videos there, that are very instructional - from the basics to the very advanced. So, please check that youtube channel out. You will not be disappointed.
Don't be discouraged. There is a lot to learn at first, but you'll get it.
And one more thing, if you are gonna start flashing roms, then you really need to buy a "Jig". Because you will need it and it will pay for itself the first time you use it.
