What would be the best type of fish and live plants to put in my 29 gal tank with my fancy goldfish

But I think the best companion for gold fish are other gold fish.

Only a few of the aquarium plant species can survive in a tank with goldfish, for example Cryptocoryne and Anubias species, but they require special attention so that they are not uprooted.

here is a list of goldfish plants http://www.kokosgoldfish.com/plants.html.

No Loollea, though the female guppy does look almost identical, I am right. though it is alway good to double check someones answer.you just never know. visits the links for proof. I know what the mosquito fish are. it is also mentioned in one of the links.here is a copy and past of it. "Two most common larvae-eating fish are Guppy and Gambusia. Both can consume 200-300 mosquito larva per day. Guppy can survive in polluted waters, while Gambusia lives in fresh water, brackish water and salt marshes. With the presence of larvae-eating fish, mosquitoes and its larva can be reduced, thus can lessen the incidence of malaria." this is the link you will find it at http://www.wis.cgiar.org/rwc/shared/asp/.

Here are the 2 fish in the Wikipedia encyclopedia.

The guppy is mentioned yet again as being introduced to some areas to keep down the mosquito population and help fight malaria.

but my answer of best companion for your fish remains the same. other goldfish.

Please note: "tropical fish" only refers to its origin and does not neccessarily mean it MUST be kept in "heated" water or it will die.
