See this recent thread which deals with both issues:
Pentax K70 or KP with the 18/135 Pros & Cons - PentaxForums.com
Note that the premise in that thread was that there was a $US200 difference in price between the K-70 and KP. With only $A100 or less between them, as there is now, there is no contest IMO, unless you absolutely could not live with the ergonomics of the KP.
See also this thread regarding the camera choices:
Which one to buy? - PentaxForums.com
Note that if you get the KP you should allow for the cost of getting a larger handgrip than the small one which is supplied. The L handgrip can be bought separately (O-GP1671 Large) from around $60, or it comes with the (expensive) D-BG7 battery grip.
If you use a remote shutter release with the K-50, it won't work with the KP. For a discussion of the options with the KP, see this thread:
KP shutter release ... Wired and Wireless options that work ! - PentaxForums.com
There are endless discussions comparing the DA 16-85 v DA 18-135. The centre resolution on the 18-135 is at least as good as the 16-85 across the range, but the 16-85 has much better corner sharpness across its range, even when both are stopped down. For many uses, corner resolution is not critical. If it is, the 16-85 is the one to get. The extra 2mm of width on the 16-85 is very handy too, especially if you don't also have an ultra-wide lens. But the 18-135 is more compact, lighter, has a handy extra 50mm reach and is much cheaper (especially in a bundle with a camera).
The Pentax DA 20-40 Ltd is a fine lens too. And it's WR. The smaller range might not be critical if you have an ultra-wide lens like the DA 12-24 or the DA 15 Ltd (I have both of these and they are both very good) and coverage above 40mm. The 15 + 20-40 + 55-300 PLM makes a wonderful kit.
Other options to consider, if you don't need weather-resistance, are the Tamron 17-50 f2.8, the Sigma 17-50 f2.8 or the Sigma 17-70 f2.8-4.

There are at least two different Sigma 100-300 lenses in K mount:
Sigma APO 100-300mm F4 EX DG Lens Reviews - Sigma Lenses - Pentax Lens Review Database - this a premium lens and highly sought after.
Sigma 100-300mm F4.5-6.7 DL Lens Reviews - Sigma Lenses - Pentax Lens Review Database - this is an average consumer lens. Judging by the reviews, it would be far inferior to the Pentax 55-300 PLM (or indeed any of the variants of the older 55-300 f4.5-5.8).
The PLM is as good as it gets in consumer-level telephoto zoom lenses. See this thread:
HD Pentax-DA 55-300mm F4.5-6.3 ED PLM WR RE - Show us what it can do, what it CAN'T! - PentaxForums.com I think this is another easy decision, given your uses. (I looked at your album to get an idea.)
