Are you saying that you took a screen shot and want to shrink it, but are
having problems with the type in the screen shot shrinking as well?

If so, well, that's just the way it works...you are shrinking the image and
taking away pixels.

Some degradation is unavoidable. First, then scaling down, you remove
pixels. Second, you're resizing in unproportional manner (1024/350=2.9,
700/300=2.3) that is also a bad thing.

There are some things you may try though:

1) Use "bilinear" interpolation rather than "bicubic". Works better for
downscaling in many cases.
2) Use some sharpening, like Unsharp Mask, before and after resizing.
3) The most tricky yet most efficient: decrease size in several smaller
steps, running Unsharp Mask between them.

If even 1) and 3) together do not work well, you just have to face it:
you're removing pixels when resizing. That is, you're removing parts of
image info. By definition, the scaled down copy contains less info than the
original, and this difference may be critical. You can't have the image
detail smaller than one pixel, that's it.
