Regarding your Questions: Is the K5 that out of date that i should not get it?
No. I just bought a second K5 [a second hand one this time as I wanted 2 cameras]
Are lenses that come with K5 worth it?
Depends on you. These are all kit lenses. They are fine for beginners. Many people outgrow them but many dont. Nobody can answer that question for you.
Is the tech in the k30 better than k5?
In some areas. See this link:
Head to Head: Pentax K-30 Vs. Pentax K-5 - DigitalCameraInfo.com
Personally I dont think the changes in tech are significant enough for that to be the difference. For its price the K30 has good features.
The k50 is coming out will price drop enven farther on the K30 or K5?
There wont be many new K5 cameras out there. So the chances of getting a better deal is low. The best deals are going to be on slightly used K5 bodies.
how do the 3 kit lenses compare to each other?
There are all kit lenses. No great differences. The 18-135 however has a DC motor that is near silent and focus is somewhat faster. Its better that way. It is also a single lens solution so you dont need to change lenses often but the reach is shorter.
As a newb i just dont know, I plan on taking concert photos inside and outside, nature scenes, macro, portrait
If you plan of taking concert photos indoors, none of these lenses will really take photos that are good but good is subjective.
A good lens for indoor concert photos will need along lens that is also fast [fast = able to take a bright well exposed picture in low light for your purposes] something between 800-1200 dollars just for the lens [tamron 70-200 f2.8 or pentax 50-135 f2.8 etc ] The 50-200 will give you more reach than the 18-135 but unless you are shooting in really good light the results will not be great. You could of course buy a long and fast lens later.
If I were a beginner I would probably just get the K30 with the 18-135 and forget about indoor concerts and shoot everything else you listed first. Once I got more familiar with using the dslr I woud rent some fast long lenses and see what works and what I could afford.
