How is this technique done with a D300, heck, hows it done at all lol I am visiting a sculpture garden soon and saw some photos online that the guy did in IR. They are stunning. Is this a camera or PS technique. Thanks :)

You can't just expect to throw a Hoya R72 on your lens and get shots like that...
Most digital IR pictures are taken with a camera that has been permanently modifies to shoot IR. This involves opening the camera and removing the built-in infrared cut-off filter (hot mirror). There are services that do this, but it is expensive. And unless you go through a service, you have to focus specially for the infrared light. Lots of older manual lenses that are compatible with your D300 have a little dot on the focus scale that is specifically for IR focus. Another thing you have to do is calibrate the white balance correctly so that your images don't come out solid red. This is easy; it just has to actually be done.
Alternatively, if you have a tripod, you can use a Hoya R72 filter combined with several second long shutter speeds to get IR images in broad daylight. But obviously since it's several seconds, you need a very still subject. The advantage of the IR conversion is you can use normal shutter speeds.
Also, most people who shoot digital IR do a red/blue channel swap in post processing, unless they convert immediately to black and white. Your second example is 99% likely to have an red/blue channel swap.

Ummmm...yes you can "throw" a IR filter on and get shots like that. Most digital IR shots done HERE on DPC I would guess were NOT done with a converted camera. We are not all rich, photographic professionals.
As you did mention, a tripod will most likely be needed (not ALWAYS), and longer shutter speeds and setting up WB helps, but if you shoot it in RAW...you can set up a profile for that, and not worry about it.
Learning post production is the key. You can put the filter on and GET the shots, just getting them to look the way you want is the tough part.

Before you do, make sure to check out if the lens "hot spots" (bright pinkish blotch in the center) when used for IR photography.
For example, the 18-55 that comes with any of the lower end nikons is excellent for IR, while as my sigma 10-20 isn't so good.
Just do a google search for lenses that hot-spot in IR and you'll most likely find excellent info. This should give you an idea of what size filter to buy as the large ones are expensive (77mm for around $200). Ebay is good for finding IR filters.
You should also check out how sensitive the D300 is to IR. The d50 has a 'crappy' hot-mirror and is therefore quite sensitive to IR and most shots can be obtained within 1s, while as to get an equivalent exposure on a d700 it takes about 30sec..
