Why do I suck?

[KhaliBear]

I'm new here and I'm not sure if I should have placed this question here or the bear section its about both sooo anyway here I go...

I read through a few bear guides which made me change my stats and skills around I thought I had a good idea of how things were supposed to be, until I tried pvp and got owned severely and a chickenrun person told me check his or her guide which brings me to my questions.

1.) Where do I go to learn to equip items from other classes and Can I equip a ring?

2.) These are my items:
Conqueror's Spiked Wooden Buckler(lvl19 pink)
Red Chain Tunic of Legend(lvl19 pink)
Iceberg Frozen Longsword(lvl30 pink)
Board and Nail of The Bear(lvl19 purp)
Redbone Warrior Helm(lvl19 Green)

My Skills:
Stomp(5)
Rage(6)
Sms(2)
Crushing Blow(1)
Iron Blood(2)
Hell Scream(5)
Evade(3)
Beckon(5)

These are my stats 1# base / 2# armor + two hand wep / 3# armor + mace and shield:
Base STR: 95 / 114 / 119
Base DEX: 59 / 59 / 59
Base INT: 1
Hit%: 75 / 83 / 84
Crit: 6 / 6 / 10
Dodge: 4 / 7 / 8
Health: 648 / 657 / 660
Reg: 3 / 8 / 8
Mana: 400
Reg: 0 / 2 / 0
Damge: 17-23 / 155-190 / 81-100
DPS: 17 / 133 / 130
Armor: 7 / 35 / 42

Up to this point all I do is quests I just go where the quests take me I usually don't leave that map until complete every quest given there.

I would like to know what change can I make to evolve my bear to PvE from total noob, I have been having an issue acquiring new items because every time I check the stats they might be more armor, health, and or dodge but always negative damage, crit, dodge, and or DPS. Should I not worry about the attributes being subtracted from my totals in exchange for more armor? I know to buff, beckon, hell scream and then stomp against wall target auto and repeat... But should I be running through pots as fast as I do? Are all monsters a little strong or have I done something wrong if so can I fix it with leveling or do I have to purchase plat?

3.) Do people use elixers in pvp?

Thank you for any and all help.
