Q1) any way pretty much, Europe is pretty flexible, possibly France, Italy - ferry to Greece, Turkey, Syria, Jordan, Egypt, Sudan, Ethiopia. Another route, Holland, Germany, Austria, Hungary, Romania, Bulgaria, Turkey, Syria, Jordan, Egypt, etc, alternatively there may be a ferry across from Greece to Egypt. There is supposed to be a service from Greece to Israel but may be difficult going that way, if the Egyptians for example realise you came through Israel I think they might refuse you entry but not sure.
Q2) No you can't drive from Aswan to Wadi Halfi, you have to get a ferry. There is supposed to be a passenger ferry that runs regularly but you have to get the barge to get the vehicles down, this can be expensive, may be $2000 for the four vehicles, not sure. Its also irregular so you can end up stuck there for 3 weeks waiting for it to get down. Heard one account where the only way of contacting the barge was via the radio on the passenger ferry. So twice a week the traveller went onto the passenger ferry for the coupl eof hours it was in and tried to arrange for the barge to come down. He did this for 3 weeks before it arrived just sitting around in the mean time. There is no open land border. Another alternative may be Saudi - they may give you a three day transit visa to drive down to Jeddah to ge tteh ferry to Saukin in Sudan. However there have been some terrorist incidents against westerners in Saudi and so you a) may not want to go or b) the Saudis may not be issuing visas, you would need to check.
Q3) You just drive, forget the name of the border but its very easy, its about 1 1/2 days drive from Khartoum, then you start climbing from the border and wind all the way up to Gondar. Really nice on the way up. Just need to check the weather for the time of year you are going. I think they have flooding up there and its a mountainous route that could possibly get blocked quite easily. They are in the process of building a good route up with the help of the Chinese but its not in place yet and instead you wind up on tracks next to the new road.
If you have time then there is some really good stuff to see on the way down such as the Krak Des Chevaliers in Syria (http://www.syriagate.com/Syria/about...schevalier.htm
) and Petra (http://www.nationalgeographic.com/explorer/petra/
