Cry from space (models)

I must say that delight was plastered all over my face when i recieved 
my new lot of cmd models but......

No 1

the NSL Battleship has 5 pieces, the 2 main structures are pretty
obvious on putting them toghether and the bridge is simple to but
those 2 extra bits have me puzzled ( the long wing bit and the hull 
section ) 

No 2 

the NSL Escourt Cruiser has a small long thin bit apart from the 
bridge, where does this long thin bit fit into the scene of things..

Can some one help me 8)
