Can anyone tell me what Astrophotography I could achieve with this set up.

You should be able to achieve some nice results with widefields. A lot will depend on the tracking accuracy, and the quality of the optics (which will determine how far you have to stop down the lens). Take a look at some of my posts in the widefield section, using a 450d and standard camera lenses. I typically use a Canon 50mm f/1.4 (needs stopping down to at least f/4) but have recently tried out my Sigma 150mm f/2.8 (works amazingly well wide open)... so somewhat similar to the focal lengths you're looking at. Mine were mounted on an Astrotrac (and prior to that an HEQ5). Mine were shot with an unmodded camera, so the mod to the 60Da should allow you to capture a lot more of the Ha emissions. 

you can get an idea of the FOV on some targets by looking

Not fully processed yet as I need more data.

This is the whole fov with this setup

If I can achieve results nearing that I will be well happy

The author rates those Samyang/Rokinon lenses very highly. There's loads of really good tutorials on his site.

Sounds like a nice tolerant rig. It should do well. While I'm very 'CCD' for telescopic imaging I think these cameras should be fantastic for widefield with thier small pixels.
