The set up you have chosen is fine. I was going to suggest a second hand digital mixer as your FOH desk but they can be expensive. The upside is fantastic automation control and integration with your laptop and they come with transparent 32 bit dynamics processors/44 bit parametric EQ's/DSP effects, on all channels. I've picked one up second hand; it's 13 years old but dang it sounds good and the processing really is transparent.
Try and use capacitor mic's. The Rode NT1-A's are pretty much one of the best budget capacitor mic's you can get - you cant go wrong with them!
Together with a nice mixer with built in dynamics processing means you can control the levels much better than having to ride the fader as the speaker moves away/closer to the mic, etc. Playing music while speaking? Then set up one of the 'ducking' profiles that will 'duck' the music as you speak.
Even if you go with the Alesis at least consider capacitor mic's. The mixer has space for four and can provide the +48V phantom power for them.
