You can go to http://www.whollygenes.com/html/uft2tmg.htmhttp://www.whollygenes.com/html/uft2tmg.htm and read the data elements that transfer using GEDCOM 5.5 and the ones that transfer using Genbridge. The report is available in either Acrobat of Excell format.
There are very few data elements in UFT that the Genbridge process does not transfer. To answer you question about the three items you asked about the answer to them is yes but there are 8 pages in the report and it is very detailed on an item by item basis. Some of the items on the list you probably did not know existed unless you are a very experienced user of UFT. Out of around 450-500 data elements in UFT only around 20 are not transfered. Some of these are redundant, some are not relevent to TMG, such as the Label for the Detail A and Detail B fields (not the contents just the label).
