Yep, the #29 should be fine and give you some good results.

Hope you have fun experimenting with the films and exposure times. 
The other variable to keep in mind is the developing technique and 
chemicals that you use to process the film.  If you use a lab. then 
you really need to make sure that they do not use infrared lights in 
the processor and that they are made very aware that they are dealing 
with infrared film.

There's lots more information in the Infrared FAQ which should be useful.
