Terry, DON'T CUT THE BEAM. It sounds like you are going to build a stud wall under the beam. If so, you can box around the beam and ducting so it looks like you have a dropped ceiling. Even moving the support posts is very dangerous. The load of your house has been calculated and the span between the posts fixed to support the weight. Increasing the span between the posts could cause sagging floors or other major structural problems. The beam dimensions have also been calculated and if you cut into it at all, you weaken the support to the whole house. If you must move a post, have a structural engineer calculate what changes you need to make and advise you exactly how to go about it. A cut into the beam even 1" deep means that the whole load has to be calculated as though the whole beam was 1" less in width.

By not consulting a structural engineer now you might save a couple of hundred bucks but the damage that you cause could cost many thousands to repair. And, by the way, most municipalities require a building permit for something like this with drawings and inspections. You should check this out as they could make you tear everything out and restore everything to original condition.
