New to KSP modding - please help!

[Czejenesku]

Hey all!

After almost two years of having KSP on my account (and awesome KSP2 tutorials) I decided to finally dive deeper than just tutorials (finally have a lot of time for one game) and head straight into nicely modded career. I decided on on contracts pack (History of Spaceflight Stock), parts for it (BlueDog, Tantares and Probes Plus) and some other things (Outer Planets, Spectra for EVE and Scatterer, Research Bodies with telescope mod, USI Kolonization and other USI packs, DMagic and Neheriam Science, Restock and R+, Waterfall, RealPlume etc).
At first I didnt know about AVC and other things, like that mods break tutorials (seen in Go For Orbit tutorial and its target marker going crazy and not working) which lead to two days in front of my PC doing different installs, adding one mod at a time and loading (imagine doing this everytime after installing parts).
I've finally made it to a point that I only get 2 errors from module manager on loading screen (connected to DV-IVA Extension and its parts.cfg file) and popup window with a conflict between B9 Part Switch and Free IVA. Bear in mind that everything works fine, at least at the start of the career and while doing tutorials (except said target marker, I know for sure that Restock breaks it, but there are mods that do this). I've written posts about in respecitve threads and now Im awaiting answer.
So why am I here? During writing posts I learned that I should link my ksp.log in a post. I also learned that you can see errors more easily in N++ with Analyse Plugin. So I did that and... my jaw dropped, all excitement just went away and my head started hurting. I discovered I have a lot of yellow and red lines. I know quite a lot of those are parts ones which I should ignore, because everything will still work (except its strange that Tantares says something about missing parts while during CKAN install it asks me to replace some russian parts) but it still worries me.
So my question is - is any of you smart Space Rascals can help me and take a look at the log? I know its a lot of text but some of you might have already encountered those and can quickly point out which problems are critical and/or wont resurface later in career playthrough.

Here is my log: https://www.dropbox.com/s/953mxs9iz4jy6xs/KSP.log?dl=0

Thx in advance and stay safe ot there!
