Generally, I advice members the safe path, in order to avoid complications, so yes its advisable to go from GB > ICS > Jellybean . You can jump from GB > Jellybean and depending on ROM, you could lose your IMEI, that's why my guide advises you to backup your efs folder first. To avoid problems, its GB>ICS>JB. up to you.
So read the tutorial fully and do the needful first before you attempt to flash.
second thing is, you are using UGKG3 modem ( meant for bell Canada) . as such, if your reception is not good after the upgrade you need to flash this modem on top of the ROM, you had chosen to get the same reception.
