MP3 and OGG are both lossy formats. Converting from one to the other (assuming same bitrates and a decent converter program) will not affect dynamics or quality.
Converting from 32bit float wav to anything else will always result in dynamic loss and artifacting. Use 32bit float if you are planning on reusing rendered items in a project or daw that accepts 32bit float. Otherwise do a good job with your mixing in the first place and render in an integer format (in this case 16bit) as CD wav (industry standard) is 16bit 44.1/48kHz. Rendering in float is typically just a cover up for bad mixing practices or when you need to non-destructively edit and render something within a project. Since anything you distribute on streaming sites will be transcoded and down sampled to 128kbps MP3, render one copy in 16bit wav (for a lossless master copy/bandcamp/etc) and then either render another in 128kbps OGG or use a converter program to convert the wav master copy to MP3 or OGG, depending on preference.
As for the original thread, MP3 is not open source nor is it public domain, and therefor can not be included in LMMS.
