Try them yourself then you'll see what they do, if you want specifics of each mod in the pack then have a look on
curse WOT mods where most of them are hosted.
Mod packs like this have work in them, he makes up an exe installer which puts each part in the correct place and then customises settings to make sure they play well together, something that's a bit of a pita to do when issues crop up.
Quick run down of the mods though:
Custom Login - its a different login screen, easy to remove
WWII Pinup Custom Garage - it's a different garage, easy to remove
Crew Pak - changes your crews pictures for ones taken from real war photos
Hit Log (outgoing and in coming damage) - A handy mod that shows both incomming and outgoing damage in a table in-game, lets you know how much damage you've been able to do so far so you can get an idea on say what your earnings will be in your nice t8 premium credit munching tank
Dead White Tanks - makes dead tanks very obvious so you don't keep on shooting them
Jimbo's - crosshair mod, athetics only but I really like it over the stock one, also adds in a 0.0s countdown for your ammo reload which is very handy for peak-a-boo etc
Scope Shadow Remover - slightly clearer view
Authentic Gun and Artie Sounds - makes explosions and shell whistles sound way better so makes the game more immersive (8.6 has improved sounds which is good)
HD Mini Map (with tank icons, last know position) - if you like to have a fairly large minimap (and who doesn't) this makes it nice and high res with clearer building definitions etc, quicker to gain info from with a quick glance. Also i keeps an indicator of tanks last known positions so you don't have to remeber which flank had what in the heat of battle.
Zoom Out - allows much greater zoom out to get a tacticle view of the fight around you, can also see over lower building to see where tanks guns are pointing to aid in peek-a-boo, very very handy mod
Accurate Damage Indicator - makes it more clear where a shot hit you from so you can angle or get in cover better, handy for those pesky invisible TDs
Stastistics (lower right showing wins/losses etc) - I think this is in your garage, when you click the flashing last battle info button it totals up your session win/loss/xp/monies which is very handy for trying to keep up a good win ratio, you can keep on playing until you hit x% every session
Wot Stastics - 3rd party app that shows you details on your battle statistics and stats for each tank, good for anyone that cares I guess and min/maxers, you don't need to use or install this part
not that lorr 51 manages to hit for over 1k each time..
Justice that is.
