A problem I'm trying to solve, JUNG switches and Z-wave

I am trying to solve this problem and I am looking for help …

Givens
======

[ul][li]The room has two lights
[/li]
[li]We are using a two wire system
[/li]
[li]There are two circuits, one for the light 1, the other for light 2[/li]
[li]There is no light switch yet installed[/li][/ul]

What I want to do:
==============

[ul][li]First I am planning to get a fibaro system or vera lite smart hub, and zwave inserts from Fibaro[/li]
[li]Then I want to buy a 3 gang light switch from JUNG this one http://www.stylepark.com/en/jung/3-gang-push-button-sensor-fd-design, first switch controlling light 1, second switch controlling light 2, and third switch should act as a scene trigger switch, with the ability to control other zwave devices around the room if needed.[/li]
[li]I want to be able to dim light 1, light 2 wont need any dimming[/li][/ul]

Questions and obstacles:
================

[ol][li]Would I be able to control light 1 and light 2 from switch 3 ? meaning if I press on the third switch, can I for example open both light 1 and 2 at the same time ? If yes, how can that be configured ?[/li]
[li]For the JUNG insert there are two models that work well with fibaro as I have been reading. Model #535 U 5 JUNG - 2-gang push-button (2 1-way NO contacts) Mechanical inserts Technology OVERVIEW and Model #532-4 U JUNG - 2-gang multi push-button Mechanical inserts Technology OVERVIEW ? Which is better for my case and why ?[/li]
[li]Do I need push buttons for a better experience ? Or retractive ones ? I would like to hear any experience in using both and which feels better especially with JUNG[/li]
[li]Does the led light work on the JUNG buttons with the zwave fibaro setup? I saw this guy JUNG 535-U5 double impulse switch with Fibaro switching - Home Automation Domotica Forum Europe, Bwired Forum saying he removed the led lights in order for it to work, but I need those lights, how can that be solved ?[/li]
[li]How many inserts from fibaro do I need to buy for my switch? and what are their model numbers ?[/li][/ol]

Thanks I appreciate it.

This is the best help request post I have seen. Clear, complete, well organized, well formatted. Unfortunately, I’ve never seen Jung switches so I can’t answer many of your questions.

Yes, you would create a scene that turns on both lights and then use the third switch as a trigger to activate that scene.

5. How many inserts from fibaro do I need to buy for my switch? and what are their model numbers ?
You need one [url=http://www.vesternet.com/z-wave-fibaro-universal-dimmer]Fibaro FDG211 Dimmer[/url] for Light 1 and one [url=http://www.vesternet.com/z-wave-fibaro-relay-insert-2-1-5kw]Fibaro FGS221 Switch[/url] for Light 2, and possibly 3.
