First off - welcome to Faerun :-) I'll try work through some questions you've asked in your application.
First off - your alignment. You can only be one, your character would only change alignment through extensive work and dedication, they cant just flip as they wish. If they are evil for example, they could manipulate situations to make their personality
appear good to trick people, but a detect alignment spell would reveal their true colours. Check out
this wikipedia entery to find out more about the different alignments.
Now, the difference between class and occupation is very simple. Occupation represents what you have either been trained to do or what you have spent a lot of your life doing. Class, however, is a character's capabilities, strengths, and weaknesses, which are all largely defined by their chosen class; choosing a class is one of the first steps a player takes in order to create a character.
For example. Your class could be a bard (capable of combat and of magic, Bards use their artistic talents to induce magical effects.) However, your occupation could be a
Adventurer. They could use their classes as a Bard to help them in their job.
click here for a class list. Only classes up to the 3.5 editions are allowed.
For example, sombody with classes as a
mage might use their Arcane skills and spells to pursue the ocupation of a
Academic and use those spells and skills to help them progress and do their job well

As with his inventory, any objects in their with magical abilities will need to be purchases with a ticket (
here is our store), and all magical properties must be described
here is all the information you might like to know about magic, from Arcane magic to Divine magic

As for the skills,
here is a list of DnD skills, though you often get skills through your class, so when you choose a class have a look at them too.
As for your history, i noticed you started it with 'recently'. Could you perhaps start from the beginning, rather than recent stuff? Let us know how he became how he is, his lifes experiences etc

Thanks! If you need any more help let me know
