EC arithmetic


I'm new in Pari. I need some instructions about EC arithmetic. 

1) GP>E=ellinit(Mod([0,0,0,71,602],1009))
Is this the only way to define any elliptic curve over finite field
F_p? What about over F_(p^n) or F_(2^n)?

2) GP>ellpow(E,[32,737],48)
    %13 = [Mod(592,1009), Mod(97,1009)]
This is OK, but is it possible to get answer only in form [592,97]?
(We know that we are working modulo 1009)

Thank you
