The website is http://www.golynx.com , you can email for schedules. I took the bus to the airport, it cost about $2 and took 1-2 hours. A cheap alternative but you have to have plenty of time.
We took the Lynx bus from MCO to the TTC last August. From the airport you can take either bus 11 or 51 to the downtown Orlando bus station, asking for a transfer as you get on. Then at downtown you take a 50 bus out to the TTC. The bus website is www.golynx.com I believe the fare is now $1.25. It takes about an hour and 1/2 to get from the airport to the TTC.
I don't know anything about the Tabernacle experience.
