I have a pair of Sennheiser HD 518 and I want to know what is a good amp or dac to use with them. I listen to music on a mp3 player and my desktop computer equally. Price has to be under 150.

The HD518 is a very efficient headphone and doesn't need necessarily an amp but you can buy a "small" amp lile the Fiio E9 for example.

I'd look into the FiiO E17, which is right in your price. It doesn't have a lot of impressions out there around yet since it's brand-new, but it's been much-anticipated.

With the E9, do I need the E7 to listen to music on my computer or is it fine by its self?

E9 will plug straight into your computers line out/headphone jack.
Even headphone amplifiers cheaper then the E9 should drive the the HD518s fairly well.
For around $25 you can get a external Fiio D3 (digital optical)or D5 DAC (USB), which should be better then the computers on board DAC.
Hook the DAC between the computer and the E9.
 
Have you checked out the new Fiio E17?
