Not having read all above I just want to add a few short tips...

Strike the Egyptian provinces Sidon and Jerusalem before you do anything else after that the Egyptians will be severly crippled...acomplishing this is easy your treasury will be overflowing in the begining and spend that money on basic troops and bribing. In my campaing I probably bought 75% of the egyptian army or more...

After egyptian crippling go on the defensive is my tip and take over Palmyra, Bostra, Petra och Dumatha one an all lightly defended...

Also try taking Harlicarnassos beneath your turkish province since it is a okey money producer and controlls a wonder. Also If you have it then none else have. A small force and a diplomat should have no problem to buy the defencive force and just move in...
