While it is true that most scholars believe that Jesus existed, outside of Biblical sources and Church histories written hundreds of years after the fact there is virtually NO information about him as a historical figure. Let me just briefly comment on your list:
Suetonius, Claudias 25.4. De Vita Caesarum
SP: Claudius. This probably has nothing to do with Jesus. All he says is "Iudaeos impulsore Chresto assidue tumultuantis Roma expulit" - literally: Because the Jews constantly made disturbances at the instigation of Chrestus, he expelled them from Rome. Scholars generally do not think that this "Chrestus" is Jesus, particularly considering that he later spells the term Christiani when referring to Jesus's followers in Nero. Note also that Suetonius was writing at least 70 years after the crucifixion.
Life of Nero 16.2
All that is said here is "Afflicti suppliciis Christiani, genus hominum superstitionis novae ac maleficae" or "The Christians, a class of people of a new and maleficent superstition, were inflicted with punishments." There is no information about Christ himself.
Tacitus, Annals xv.44.
The quotation here is a bit longer about the Christians being blamed for the great fire of Rome during the reign of Nero, but all that is said about Christ is this: "Auctor nominis eius Christus Tiberio imperitante per procuratorem Pontium Pilatum supplicio adfectus erat" or "The man who gave his name [i.e., to the religion], Christ, was put to death by torture under Pontius Pilate in the reign of Tiberius." But the superstition did not remain in Judaea, the "origin of its evil," but spread throughout the Empire. Written only c. 112 AD.
Pliny the Younger, Epistles x.96-97.
Pliny merely asks the Emperor Trajan for clarification as to what the crime of being Christian is and what punishment it entails. There are no details about the faith or its founder. Written exactly in 112 AD.
Josephus, Antiquities 18.116-19
This passage has been heavily tampered with and it is uncertain whether Josephus wrote ANY of it, given his pro-Roman sympathies (he certainly did NOT write the short, terse sentence "He was the Messiah" given how he writes about the Messiah in the rest of his works).
Eusebius, Origen and Justin, aside from having written even later than the above-mentioned sources, are also devout Christians who are repeating what they have read in the Gospels. They are NOT contemporaries and should not be taken as such.
The citations to the Talmud which you provided are even less helpful. One "reference" to Jesus is to Yeshu ben Pantera (Jesus son of Pantera...didn't know heavy metal had been around that long), and the only reference that provides any factual information is the short one which says "On the eve of Passover they hanged Yeshu because he practiced sorcery and enticed Israel astray."
This is not exactly copious evidence of Jesus's teachings, his followers or the basis of Christianity as a belief system. About all you have written within 100 years of his death, outside the writings of believers, is a short phrase by Suetonius in Nero about Christians, a short paragraph in Tacitus that says he was put to death by Pilate, a couple of very suspect remarks in a text by Josephus and a line in the Talmud.
That's not as much as your list implied.
