You're not going to find anything worthwhile that includes the features you require at your price point. IMO.
That said, the Brickwall and SurgeX devices are good suggestions for surge protection, although neither has the coax and telephone line inputs you require.
Also, IMO the Brickwall may be a good surge protection device, but I would not look for it to do anything magical as far as the sound of your system is concerned. I own one, and essentially it's sonically benign.
