Apart from not exposing the film to any sort of heat, loading and unloading in the dark (ideally). You still need the filter as IR film is still sensitive to other wavelengths and to compose and focus without it as you can't see through the filter. Then adjust the focus to compensate for the difference in diffraction of IR radiation on a tripod and 'guess' the (probably long) exposure. An IR modified digital camera is far easier to use and to get good results from. In fact, even with their IR filter over the sensor, many digital cameras are sensitive to near infrared and you can get great results from using a very dark red filter (have a look at the ones Chris posted). The Leica M8 had no IR filter and so is even more sensitive and in fact you ideally near an IR block filter to get some textiles etc to render correctly. Give it a go!
I'm always mindful of a photographic quote though, "A photographer is someone who knows how to use infrared film, but chooses not too!". I find the novelty soon wears off (although B&W IR can produce some lovely tones in figure studies.
