It's doubtful that the character described in the gospel accounts (at least the canonized NT accounts, there are some 47-52 other "gospels" that weren't included at the time of it's canonization) was a buddhist or knew anything of the Buddha. It appears that the synoptic gospels present a Jesus that quoted from the Tanakh on a regular basis, often citing numerous verses from Isaiah. There are very few hints of any buddhist type figure, really, just a few similarities. If anything the Jesus figure more closely resembles the Mithras or Dionysian cults, and possibly a few earlier Egyptian deities. In fact, most astrological type deities all stem from the same ancient Sumerian and Egyptian religions, and there should be similarities as the tales were passed from one generation to the next.
However, in regards to Jesus being any different from the YHWH figure of the Hebrew canon, I beg to differ. The character is quoted as being quite divisive, (Mat 10:34-37) and quite adomant about supporting the YHWH figure's Torah (Mat 5:17-20).
