If you've got a newer version of LabVIEW (6.0 or greater), you do not need the toolkit to view VIs in a browser. LabVIEW 6.1 added the ability to view and control VIs. Under the Tools menu, see if you have a Web Publishing Tool. If you do, click the Help button to get details on how to create the web page and your various options. LabVIEW comes with it's own web server that needs to run and to control a VI from a browser, the LabVIEW run-time engine needs to be installed on the client pc. For multiple clients to have control at the same time, you may also have to purchase some additional licenses.
If you have a much older version of LabVIEW, then I would recomend the book "Internet Applications in LabVIEW" by Jeffrey Travis. You can get the book from
Amazon or go to his website
here.
