When it comes to zooms, my opinion (others may well differ, I am increasingly anti-zoom!) is that the smaller the zoom ratio (40-80 would be 1:2, 80-320 would be 1:4) the fewer the compromises that have to be made, and therefore the better the end-result.
Bear in mind, that although a lens may offer a nominal fastest aperture of say f2.8, it does mean that it will be any good at that aperture. Nearly all lenses are at their worst wide-open.
An f4 lens which performs reasonably well wide-open is a better bet than an f2.8 lens which is lousy wide open.
However, such problems may not be very noticeable with the kind of subjects you shoot. Since the lighting (I assume) is likely to be highly unnatural, viewers might well accept imperfections which would not be acceptable in a picture of a building.
My advice would be to analyse what is going wrong with your worst shots, and also try to decide what facilities are absolutely essential for you, and what focal length(s) you mainly shoot at (or would like to). You may find that you could buy a couple of inexpensive fast prime lenses and that they would do a better job for you than a slower, less sharp, zoom.
Good luck

Manual focus is not a major disadvantage, especially on a fast lens (which lets in a lot of light when you are focussing).
As a generalisation, fast zoom lenses are either very expensive or not very good.
Just about the fastest lens you can buy for the camera at reasonable cost is also the best and amongst the least expensive. It is the 50mm 1:1.7 Pentax-A. Manual focus, but one of the finest lenses ever made for any camera at any price. The FA version (autofocus) is optically the same, but much harder to find. The 1.4 version is also superb, but much more expensive.

Buy one of the photographic magazines to get a rough idea of price differentials, then buy on Ebay (with care!).

To cut a long story short, you must uses lenses which have an "A" setting on the aperture ring, next to the smallest aperture, normally f22.
Any Pentax lens called "A" or "FA" or "FAJ" will work, as will most non-Pentax lenses (with a K bayonet mount) with the "A" setting on the aperture ring.

I've owned both, plus the original ME (and loads of others), and there is no doubt (IMHO) that the Super A was by far the best manual-focus Pentax with both auto and manual exposure.
Don't people do their homework?

There's not really much point in looking beyond Pentax. With the exception of Vivitar Series One, no other lens manufacturer is likely to come near Pentax for quality, and there is no shortage of Pentax lenses. This was their golden age.
Make sure you get a standard 50mm lens. They are optically superb, and very cheap.

When you find the entry, you will see just a brief sentence saying the lens is a little soft, but click on the URL above and you will get a lot more detail.

It's well named; it's a super camera. I've owned six different Pentaxes and this is my favourite. Its facilities can't compare with those of modern all-electronic, all-singing, all-dancing cameras, but it has everything you need.
It's not as robust (or as expensive) as the MX or LX, but it has both aperture- and shutter-priority auto exposure for when you need it, which those two don't.
