Forward + R1 at the same time breaks the guard of enemies who are blocking with a shield and leaves them open for a counterattack.
You missed his sweet eagle drop intro. That character is like nemesis, he appears suddenly to kill you. Where you fought him is an early opportunity to beat him, but you only get one chance. Once you got knocked off he considered you a coward for running away, and phased out. I assume the reason those 3 enemies don't stand up during the fight is they are scared of him as he hunts all undead.
Can use items through inventory screen (one to the right of equip screen), don't have to equip them first.
Shield explanation
Ignore the left hand column, that's for when using the shield as a weapon.
Right hand column
the first 5 numbers represent the % of the damage that is blocked when you hold your shield in a guard position.
1st is physical (non-elemental) damage, 2nd is magic damage, 3rd is fire damage, 4th is lightning damage, and 5th is dark damage.
Physical is the most common type of damage in dark souls so it's good to use a shield that has a 100 rating for the first number, that means you will take zero physical damage when blocking that type.
The next four numbers are less important. How status effects like poison work in the game is when you get hit by it a meter starts to fill, if you get hit enough times with that status effect in rapid succession then you will be inflicted with that status effect until the meter slowly goes back down to zero. Those four numbers slow the rate the various meters go up when blocking (poison, bleed, petrify, and curse). I mostly just ignore those numbers when deciding between shields.
Sandwiched between those four numbers and the durability amount is the stability rating. This determines how much stamina is depleted when you block an attack, the higher the number the less stamina lost per blocked attack.
If at any time you forget what the numbers mean, or are unsure what anything on any of the menu's is, press select and a cursor will come up which will tell you in more depth what a stat does.
