The Sigma 15-30 & Sigma 28-70 are lenses that compliment each other not replace each other.
The 28-70 is a constant f/2.8 lens and goes pretty wide, good for most portrait work.
The sigma 15-30 on the other is not a constant aperture and the lens is too wide to use for portrait work.
In your case I would look at the 17-70 offerings from Pentax and Sigma.
Another option is to see and wait how the Pentax 18-135 would be.
btw you've the Pentax 28-80 3.5-5.6 and Sigma 18-35/3.5-4.5, aren't those good enough?
If you're looking for high quality than the Pentax 16-50, Tamron 17-50 Sigma 17-50 would be your better bed.
At 50mm you can do portraits easily and they are all constant f/2.8

I agree, I do think your lenses cover the range.
The only upgrade you could have is a faster lens.
I would go for one of the 24-75mm, 28-75mm, 28-70mm f2.8 tammy or sigma as they will cover a nice range for wedding parties (50mm is sometimes a bit short for portrait I think)
Otherwise as mentioned by Anvh 16-50, 17-50 f2.8 would be the best ones.

thanks guys, I'm thinking about Tamron 17-50, and it gives far better IQ.
Boudou701 what can you say about your Tamron? Specially the AF speed.
I thinks I get Tammy for parties, and Sigma 28-70/2.8 for portraits.

Sigma 15-30 is a very bulky lens - I'd go for the 16-50 or 17-70, it's not often you want to go as wide as 15 mm

Pwynnej what do you think about sigma 28-70/2.8? or maybe buy tammy 17-50/2.8 + Sigma 50-150/2.8? bit more expensive but gives cover for all occasion. Unless I'm wrong. thanks again

Had the 24-70, very good lens which has a slightly longer range than the 28-70... Get a good copy you'll have a very good lens...

Okay, thanks for that, but are they "useable" for like weddings, christening or so, with APS frame, or is it better option to grab Tammy 17-50/2.8?

really depends on what you want it for! if you want to take a shot inside the church, you'll definitely be happy to have the 17-28 range, if you only want to shoot portrait types outside, you might want to go for the 50-70 range.
the 17-50 + 50-150 you mention is what i'm ultimately aiming for, now i only have the 17-50 as no money for the second lens.
try to think about what you're going to use the most, if you were to choose one lens, I'd personnaly go for the 17-50 as I'd rather crop the photo after than having a missing arm on my picture - that said the 24-60/70/75 could be a good compromise.
Good luck with your choice and check the pentax forum database for lens reviews by users, it'll give you an idea of the lens limitations.

Get the wider lens for now, at 50mm you have a short telephoto lens very usable for portraits.
When you're getting more into portraits you can get the 5-135 or 50-150 to fill the spot.
I went the other way, bought the DA*50-135 for portraits first and then bought the DA*16-50 for normal photography.
The two lenses at those ranges work very well together, at least for me.

Or maybe just get both?!
I'm asking for help.
Cheers
