That's the toughest question yet, as I have absolutely zero experience with Sony lenses.
However, for static subjects, you can get away with slower lenses. It's nice to have a wide angle for scenics.
The most important thing I can recommend you get is a good tripod and some type of remote shutter release, either wired or wireless. Especially with sunsets, it's good to stop down your lens (larger f-stop) and increase your exposure which will help with colors.
The general rule for shooting handheld, assuming you are practicing good techniques, is to shoot faster than the inverse of your focal length. So if you are shooting at 200mm, you would want to set your shutter speed at 1/200 of a second or faster. This does not take into account any type of stabilization your equipment might have. You can lower this by a couple of stops if you are braced up against something or resting on something.
If your camera is mounted on a sturdy tripod or other support, you can go as long as you like, except as noted in above posts. The only things you might watch for is vibration from your hand depressing the shutter (which is why I like remote shutter releases), and shooting around 1/15 of a second. I don't know how much this would really affect the average shot, but the theory is that the mirror box assembly frequency is around 1/15 of a second and you would get more vibration at that speed.
What I would do if I were you is go play around and take a lot of test shots with the lens you have and see how you like the results. A lot of photographers tend to focus (pun intended) on certain subject matters more than others. Find out what you like and then plan your future purchases accordingly.
Just my 2c worth,
