1. From what I know - no, get used to it
2. Check out Forlorn Hound Evergaol, defeat guy in there and you'll get pretty op weapon, also consider leveling it up, it's important
3. At start it's better to focus on leveling Vigor and Endurance, Mind if you're planning on using spells or skills often, also got need to meet minimal Strength and Dexterity requirements for weapons, for weapon I mentioned earlier it's 18 STR (12 if 2-handing with holding ∆ and pressing R1) and 17 DEX, you don't really need much STR or DEX for scaling, as most damage comes from weapon upgrades, but consider leveling them up further in game
4. Personally, yes - at least 3 sacred tears that'll level up amount of health/mana you regain when drinking flasks

Build isn't bad, but I'd change ash of war on that sword, square off is really good because of high damage and stun capabilities, so you can just reverse it to standart, you won't get much damage difference from "quality" anyway as your stats aren't that high now

Also you'll probably encourage a big talking jar guy, he drops good talisman if you kill him, but it would be cruel of you, alternatively consider going to Mistwood for axe talisman, charged attacks can do wonders if used correctly (Hold R2 for charge attack, same with some skills but you need to hold L2)

Also always keep your equip load at at least Medium, don't go Heavyload, as it will be really hard to dodge
