We are having trouble with the sound being too low. We are using a LTIBLOX adapter in order to use a table microphone as well as a wireless lavalier for recording. Are there special settings we should be setting up in Audacity and if so, where would we find them? We have the output level and input level at the maximum.

If you mean this device: http://www.rapcohorizon.com/p-377-ltiblox.aspx
then it's an output adaptor, not an input adaptor.
It converts input from consumer grade equipment (laptop computers, MP3 players, CD players) to a mic level balanced output
I don't understand how you are intending to use this device "in order to use a table microphone as well as a wireless lavalier".

The LTIBLOX plugs into the laptop then we have an adaptor that allows a y cable so that we can plug in a table mic and wireless lavalier. We would like to record a Speaker within a meeting.

I think you are using the LTIBLOX incorrectly. It is designed to reduce the output from a computer so that you can connect it to an XLR microphone input. You are trying to use it the wrong way round.

What you really need is a MIXER, or a USB interface with two microphone inputs.

You need to select a mixer with the correct connections (Low impedance balanced XLR ???). And, normally the mixer will connect to your computer's line-input (with the appropriate optional adapters).

If you are using a laptop without a line-input, you need to get a mixer with a USB output.

Here is an example of a USB mixer. (It's just an example, you don't need this many inputs.) Here is an example of a USB interface with a couple of XLR mic inputs.
...that allows a y cable so that we can plug in a table mic and wireless lavalier.
You cannot connect two outputs together with a Y-adapter... Each device puts an improper impedance load on the other device... You need a mixer in order to mix two signals. i.e. you can use a Y-adapter to connect one CD player to the inputs of two amplifiers, but you cannot use a Y-adapter to connect the outputs of two CD players into one amplifier...
