Flight
This is the closest and easiest airport in Houston. There is also Bush continental Houston, and you could fly in to Dallas (4 hour drive) or San Antonio (3 hour drive) if that is easier or you're looking to expand your weekend in Texas.
House Or Rental
There are plenty of places to stay in Houston and an Airbnb is a great way to stay for cheap but feels like home. The venue and church are on a light rail inside of Midtown, Houston. Houston is incredibly large so make sure to check the travel time when booking
Hotel
There are many hotels to choose from, the wedding is next door to minute maid stadium so you may want to use that as a reference point when booking a hotel. Anything in Midtown will be relatively close to both the reception and the wedding locations.
