I can find it, and extract lots of data fields, but I cannot determine some more information such as distance to the star and proper motion. Can anyone extract this information for me, please? Thanks.
Did you try VizieR? All the fields have explanations, but I can't see a distance. Anything beyond about 1000 parsecs is unlikely to have a distance unless it is a periodic variable like a Cephid.

Aladin (requires Java) has an image here. (Hope that doesn't have a cookie and works.)

If you start from http://vizier.hia.nrc.ca/ select Tycho-2 catalog, put the RA and Dec in the "Target" box, at the bottom of the result page are the Aladin links.
