PIX Failover and Redundancy switch replacemnet

I have got this scenario :

Outside (internet)?switch 1?Primary PIX?Core1-----LAN

Outside (internet) ?Switch 2?Secondary PIX?Core2-----LAN

Switch 1------Switch 2 (connected via Ethernet link trunk)

Primary PIX------Secondary PIX (connected through failover cable via serial interface)

core 1------core 2 (connected via ethernet link trunk)

VPN concentrator is connected between switch 1 (active) and core 1

We have got active outside switch 1 (2950) , active primary pix (525) , and active core 1 (4000),,,,,

And also we have got inactive outside switch 2 (2950) , inactive secondary pix (525), and inactive core 2 (4000).

Redundancy has been taken in consideration

1- If primary PIX fails, the standby PIX (secondary) will take over (obvious), now does core 1 (active) will be replaced by core 2, because secondary PIX takes over ?

2- In the similar way does switch 1 (active) will be replaced by switch 2, because secondary PIX takes over?

3- Does the same thing happen to PIX, if switch 1 fails or core 1 fails? (i.e. if switch 1, obviously switch 2 takes over , does that mean the primary PIX will be replaced by secondary one )

4- If VPN fails, Shouldn?t there have been redundancy? (i.e. Is this a drawback in design) ?
