i would go for a 4.6 every time am currently building one for myself and have just done one for a customer see my web site.
as regardes the ecu are you on hot wire fuel injection? if so no problems if not then factor this into the upgrade the 3.5 flapper is very limited tunning while the 3.9 hotwire system is better ans will adpt to the 4.6 lungs
