Pumping VIT or END early is always a good idea. Let’s you live longer and equip more/attack more. A good rule of thumb I follow is 16STR/20DEX before I pump any other stats. This mostly applies to DEX builds since most if not all DEX weapons require at max 16STR (Chaos Blade and Lifehunt Scythe for example). Then depending on how you want to make your build, you can keep DEX at 20 or bump it up to 40.
Also while we are on the topic of stats, you may or may not know that 40 is the cut off for many stats as going above will subject you to diminishing returns. Some more severe than others.
Redundant info for some; new for others
[details=Spoiler]Vitality - Flexible stat. You can make it as low as 30 or as high as 50. More examples of diminishing returns; 30VIT - 1100 HP, 40VIT - 1325 HP (+225), 50VIT - 1500 (+175) HP, 60VIT - 1588 HP (+88).
Attunement - This is preference. I would personally never go above 19 just because 5 magic slots is more than enough.
Endurance - Stamina gain caps at 40. Unlike the other stats however, this is not subject to diminishing returns past cap. Every point about that will increase weight burden by 1 point. Essentially, the higher the END, the fatter you can be while rolling.
Strength - It can be raised to 50 if needed to one-hand the heavy weapons such as Dragon Tooth, Dragon Great Axe, or Grant, otherwise 34 can be the bare minimum for two-handing such weapons. Take note though that the highest requirement for a STR weapon is Smough’s Hammer at 58.
Dexterity - Must be capped at 40. To explain it as simple as I can, Chaos Blade scales with Humanity, up to +10. A +5 Chaos Blade @ 40DEX/10Hum, it comes out to 450 attack rating. The same +5 @ 50DEX/10Hum puts the sword at 455 AR. As you can see, you gain 5 rating for 10 stats, not a great investment.
Resistance - Useless because you get defense points just raising other stats.
Faith/Intelligence - Diminishing returns aren’t too bad. They can be raised up to 50 for maximum damage benefit. Otherwise you go for bare minimum for the spells/enchants/equipment you want to use (30 for Crystal Magic Weapon, 44 for Crystal Soul Spear, 28 for Wrath of the Gods to name a few).

Hopefully this helps any new guys that have any questions about stats as well as anyone else that may have wondered about them.
