With myth one, the only technological advances that I heard about was the T-34, even though that was a AMAZING tank, it is true that the Red Army won a lot of battles at least partially because of tons of bodies.
Myth two, no. Russian winters are MUCH colder than anywhere else other than somewhere like Antarctica, not all places have the same temperatures, and the German army hadn't planned on battling the Russians in the winter, they had planned it to be a quick operation that they could get done before then, so it did cause huge amounts of damage to both the physical army and their morale.
Since i wrote some papers on ww2 history and generaly read a lot about that topic let me list a bit more.
Germans were far ahead in 1941-43 in terms of army organisation, radio, optics (in tanks), had slightly better air fighters and bombers.
Russians in 1941-43 had better tanks (T34 and KV-1 were vastly superior to pz2-pz4, better personal weapons - namely the more reliable PPSH etc.).
Guns, fleets etc. were comparible.
In 43-44 Germans had better tanks, for a limited time (until T3485 and IS2 appeared which were comparible to Panther and Tiger\KingTiger in effectivenes, although not as pretty ,and were better suited for mass production)
In 42-43 Russians began to have comparible fighter aircrafts (La-5)
Also there was the IL2 attack aircraft, "the flying tank" which none of the other nations did have.
Also since 42 the russians had devastating rocket artillery "Katysha" BM-13 launchers.
etc. etc.
In general both armies had their aces in the sleeves and were technologically comparible. Some better at certain points etc.
Now about the winter, it is true that it was planned that the Barbarossa would end before winter, although as i mentioned before, Russians suffered exactly the same as germans (entie regments freezing to death), and at certain points were supplied even worse than germany with winter gear. Russians do live in warm houses, you know, and winters there are not generally colder than anywhere else. (Unless go to nothern syberia... where there were no germans).
By the way, fighting in spring was even worse than in winter for both sides, from the logistics point of view.
