First of all no-one knows the real capability of Netra and Erieye other than their user and manufacturer. Second most of the AWACS uses 'S' band radar, 'X' band are always airborne fire control radar. Third you don't need special fire control AWACS to cue the air to air missile, for that you need two way datalink in the missile. Like AMRAAM, Astra too have a two way data link. Netra can easily cue Astra.
No you cannot judge Mk2 from Mk1a as both are pretty different. Mk1a don't have MAWS and also it's using underslung Isreali EW pod whereas Mk2 will use indeginous internal EW pod and MAWS. MK2 isn't in paper anymore, it's construction has already begun.
AMRAAM is not the best missile and in this age standard propulsion is not enough to always hit a manuverable target, for that meteor's throttleable ramjet is more than perfect. And we are very close to develop a Meteor equivalent of our own
I don't know how advance Sweden's data links are but AFAIK they are using Rover data link from L3haris which is a american company. Rapid firing is no out of the world capability, many aircraft can easily do that. MK1a can also do that.
You have many misconceptions/no idea about many systems and also have inferiority complex.
