While browsing a few years back, I found myself buying the Blue Snowball. While many headsets now include good microphones, I chose this one because it was (and still is) cheap and of good enough quality for regular use.
As for the input settings, that might be tough if you have no experience with it. Depending on your laptop's OS and the wide range of software it might be tough.
Before any audio settings in place, test out your audio with:
- a microphone,
- a physical filter (some uses socks, its not recommended but it's just to give you an idea of what it is),
- a room with as much noise reduction as possible (thick curtains/room with a good amount of furniture/sound absorbant panels, all of those can help).
Chances are, the noise will still be too much and you will want some artificial changes from softwares afterwards, but the more you dampen the noise, the less tweaks you will have to do in the software making it easier while also not ruining the audio too much with software filters.
If you're willing to tell me what OS you will use with that laptop I can try and see what could potentially work on there without just telling you xyz software and giving you random values you have no informations on. Sometimes, simple OS audio configurations can do as much as some advertised software.
