Not in any particular order, some thoughts/answers...
Mixer - example: Alesis-8 USB - but it's £129 (Maplin, UK) but Alesis a World Brand should be available locally. However, this is 8-inputs and needs a USB-input PC/Laptop. Personally, I think you need to try that Panasonic voice-recorder -and- sort out the sync issues.
If you know an electronics friend he'll be able to make you a 2-ch mixer for a quarter of this . . .but the Alesis may come bundles with Cubase LE software, which would be useful for a small music group... for future use?
PalmTrack and Zooms are good for music recording(CD-quality), but I think it's an overkill - at least until you try that Panasonic - indeed I'm surprised you haven't done this as it would take so little time - less than writing a reasoned reply.
Lavallier mics sling round the neck - Do you really want tie-clip? (as used in News Reports, etc.) - they are a variety of prices, but need not be expensive for speech-only. Expect to pay £20-ish - but watch the lead-length and plug, so it fits whatever recording means you choose (this is a nightmare!). Pro-quality tie-clips are £120 but are much better/stronger/smaller..... some include a pre-amp as well.
I think you need to do some experiments with what you have - then let us know how it meets your needs...
