| Is there a process in PSCS to achieve IR effects if not can the D70 produce IR shots with the Hoya filter? |

You can defintiely process for an "IR look", but the results will not be entirely convincing. You can certainly shoot with an IR filter on the D70, however I suspect the exposure times will be quite long. Most DSLRs have quite efficient IR rejection filters in place, with the exception of those specifically designed for that type of imaging, like the Canon D20a (which is meant for astrophotography, but would also be great for IR landscapes).

I like the Wratten 87C filter. Works nice...

To process in PS for an IR look, have a look at the actions available fron Fred Miranda

I have PS7, not CS but it should be a similar process. Here's the process according to eDigital Photo magazine.
1. Open the color file and convert it to black and white using a channel mixer adjustment layer. First check the monochrome box then start playing around with the sliders. Try setting the red all the way to +200, then take the blue down to -60 or -75. The green middle slider might go from -40 to +30 depending on the image. Adjust to taste, but you'll probably want to keep the red at least +100 or +120 minimum.
2. If you have adjusted the sliders for a look you like but the image is dull or low in contrast, try adding a levels or curves adjustment layer to pump up the contrast.
3. If you want the IR glow found in IR film you should flatten the image and then blur the image with Gaussian Blur. The radius amount will vary with the size of your file, so experiment. As a starting point, try 5-20 pixels for a 25MB image and 2-10 for a 5MB image. Next, fade the blur(under edit in PS7). Change the mode of the blurred channel to Screen or Overlay. Adjust the opacity slider to taste.
4. You can add noise if you want the gritty look of IR film.
5. You can also experiment with Filter-Distort-Diffuse Glow. It sometimes adds a lot to your photo, but you have to be careful not to over use it.
Good luck!

You can shoot IR with a filter, and have great results with the D70. Did some last weekend, messing around. But have shot a bit before also.
You will never get the real look and feel (in my opinion) through software for IR.

Check out this web page from Robert Williams web site.
He explains how he achieves IR photography with his Nikon D100
