The erroneous warning lights are often associated with the battery. If the battery itself has been replaced, the next step for me would be the battery negative chassis lead (the lead that connects the ground to the chassis directly under the battery), it is a known issue, coming loose or corroding.
As a short cut, try connecting a jump lead from the battery negative to any of the usual chassis/ engine ground points. If it is this it should start no problem.
I had a similar issue (though it never caused an issue for me once running), and that was the wiring to the low pressure pump (in the fuel tank).
When you put the key in you should hear the slight buzz of this pump coming from the back of the vehicle for around 10 secs.
The issue appears to be in the fuse box (by the drivers knee), the wires seem to go in there, not do anything, but then come out. The connection in the box was dodgy.
I didn't get any other warning lights, but if other connections are dodgy, this could be related. Worth investigating, the guys at Alfa workshop diagnosed it for me after I took mine in thinking the pump itself had failed, they said they'd seen it before.
If you have a copy of multiecu scan, (free and £5 for a OBDII plug), you will see no fuel pressure when you put the ignition on.
