Q2: I often see players on the same class as myself use skills from other classes, how are they able to do this?
A: Certain skills are listed as cross-class, check skill description which ones. These skills are equip-able on all base classes. You get 1 equip slot for every 5 levels. For Jobs, they are restricted to 2 class only plus your 1st 5 skill slots are taken up with your Job skills, that are learned as you do your job quests.
Job List:
Warrior: lvl 30 Marauder, lvl 15 Gladiator. Can use cross-class from sub and Pugilist

Points for putting some in Str.
1. STR effects your damage reduction from parry/block in addition to higher attack damage
2. The extra damage will help you tank better during early levels by helping hold the Hate with your higher damage output.
3. The current threshold for maxing you damage reduction with coil/myth gear is 9 bonus points in STR.
4. These points can be respec-ed easily with an item that cost 10,000 seals at your GC. There not much to spend your seals on unless your doing crafting, but even then as long as you do the daily GC supply/provision for all the gathering/crafting class you will get enough seal to cover your xp manual costs.
