Tidus what kind of weapon do you mean? cause I gave you the list of weapons with which a rogue is proficient already.
Arcane if you want to be good with ranged weapons you need a high dexterity score instead of a high strength score. Keep in mind however that the sorcerer class relies on spells a lot more than it does on normal weapons (altho there is a special PRESTIGE CLASS which combines the two. it's called Arcane Archer (nice coincidence) Prestige classes are classes which you can only take after you meet the prerequisits which are quite a lot so don't worry about that now)
Okie now your skills
you have 16 skillPOINTS
with these points you can buy ranks in skills. Some skills are more suited for a sorcerer than others these are called class skills and are: Bluff, Concentration, Craft, Knowledge (Arcana), Profession and Spellcraft. all other skills (found on page 3) are CROSSCLASS SKILLS and which cost twice as much (two skillpoints for one rank) you can give out 4 skillpoints per skill as a maximum
