You will get no benefit from something like a cheap 19-35mm over the 18-70mm kit lens. It is actually much better than many people think, particularly at 18mm where it has much less distortion than most similar kit lenses. If you want a wider angle, there's a choice of two - and that's pretty much all. It is barely worth buying a 15mm or 14mm prime from Sigma or Tamron, or a Sigma 15-30mm zoom, and you probably won't want to upgrade to the CZ 16-80mm ($700 lens). The choices are the KM/Tamron/Sony 11-18mm f4.5-5.6 (all are nearly identical, KM is discontinued, Tamron version is lowest cost) or the Sigma 10-20mm f4-5.6.
I've used both types (the Sigma on Nikon not Minolta/Sony though) and my preference is for the Tamron-type design because of the way the distortion is handled across the frame. It's just that little bit better for professional architectural work. But the Sigma is good, and may be 2/3rds of the price.
With the kit 18-70, your Apo D 100-300mm, and an 11-18mm you pretty much have all the lenses you will need short of very long or very wide aperture.
