time to load is also depending on hardware and load on server. I'd say, the least queries the better. Each query is extra load for the server. If you're alone on the servr, not such a problem in most cases except if you have about 10k simultanious users asking pages... 29 * 10k will stress the server greatly and end in slow page generation.
Next to that, even if you page is generated (server side) quickly... I can't care ;) I only have a 56k line... means I have to wait around 15 secs to see something in any case :-)
basically, I always advice people to reduce the number of queries as much as possible. I admin a server hosting a pretty heavy site (server is low end) and we did tweak all scripts to use least possible resources and it runs smooth for all visitors. he same scripts in basic setup killed the server months back.
Regarding the site to measure +/- your webpage that brandon mentioned
Web Page Analyzer
don't take this for exact science but it'll give you good results to work on
