Ok, I think I successfully rooted my phone. I Installed titanium backup in it says OK (busybox 1.18.4) to root access. Is everything allright now ? 
So, what about ROMs ? what are the best ROMs ? I kinda liked htc Sense so I wouldn't mine a Gingerbread with sense ROM again.

Should be OK. In TB, press Menu>Batch>Backup all users apps + system data to backup your apps. To restore the apps once you install a new ROM, select 'Restore Missing apps and all system data' instead.
Now before you install a new ROM, I advice you to format your SD card and create a new ext3 partition, preferrably of 1Gb in size. This will let you run A2SD+ or DATA2SD ROMs. If you use Linux, then you can use Gparted to partition the SD card.
Oh BTW, do you know how to boot into the recovery?
