1) Depends on your budget

2) huge different if city travel is primary
But take note, there's no fuel savings. The premium pricing on the EHEV can buy many liters of fuel

3) EV motor primarily with the ICE as range extender/power assist

yes and no really.

the battery is small, so if the ICE need to constantly charge it, it won't be effecient anyways.
the key is how good the regenerative braking is in charging the battery.

but in very simple answer, yes, its main propulsion is EV, then ICE as supplementary and charging the batteries.
that's why on highways, it isn't that efficient as the roles has switched that EV is too weak to maintain higher speeds, and the 1.5 ICE isn't exactly high powered to maintain efficiency at higher speeds, so but lesser of evils, the ICE will switch being primary and run almost constantly all the time.

Depends on you.. Both are technically the same. The cost eHev (RM 141,900.00) vs V (RM 135,900.00) ~RM 6000. eHev I heard get 700+ km (Full tank RM 75/36L). Turbo: About 400+ km.. (Depending on foot)... So yea.. But eHev.. Less burden if gov decided to uncap fuel price.
