Lunn's page

As we all know the underdog race of this game are the fabled Kobolds who are known as trapsmiths and other things.

So I have this Male Kobold Rogue 7 / Trapsmith 5 / Kobold Trapsmith 5 / True Kobold Paragon 3. His name is Lunn-Lunn and he has the following which will bring us to a question:

Extraordinary Trapsmith (Feat)
If a kobold picks up this feat the cost and time for a trap is reduced by 50%.

Skilled Improviser (Class Benefit)
The Kobold Trapsmith gets a price reduction on his traps by 10% at 2nd level. This increases at 5th level to 20%

Trapmaking Expertise (Ex Class Benefit)
The traps cost 75% their calculated price and 1/2 the time to create.

So here is my questions comes in:

1) Do I only have to pay 5% the normal price to create ANY trap I could make? Like for instance a 1050g trap featuring 3 Mwk Heavy Crossbows only costs 52g to actually create?
2) The above advanced trap (The Bolt Trap) given to you by the Trapsmith class states it takes 2 rounds to set this trap up. Yet, with all the trap shenanigans Lunn-Lunn has, would he be able to also set up a second or even third Advanced Bolt Trap in the same round?
(Lunn-Lunn halves the time required to craft a trap twice and then he cuts that time by 1/3rd)

So a friend of mine brought to me one day an interesting character since we were going to start as 4th Level characters and I was the GM. It was a Male Human Sorcerer 3 / Monk 1. He dabbled in the area as a Wrath Bloodline Sorcerer with a mix of the Dragon Bloodline with the help of the "Dual Inheritance" feat. He had taken the "Improved Natural Attack" Feat as he designated Claws for the target of the feat as both his Bloodline Powers make his hands into Natural Weapons with a Free Action. He asks me if he could stack the three separate areas that treat his hands as weapons (Monk's Unarmed, Draconic Claws, Wrathful Fists). So I would normally say "No they wouldn't as you would take the strongest one".

So the big question is can he actually stack the 1d4 Wrathful Fists, the 1d6 Draconic Claws, and the 1d6 Unarmed Strike for the grand dice total of: 2d6 + 1d4 + Strength

It is also a bit of curiosity on my part of wondering what a character is "Limited" to.
