Bonus XP
Don't forget to add 10% to your XP, if you qualify for the bonus for having a prime requisite over 15.
Spells
You roll starting spells according to the chart on p 39 of the DM Guide, starting with Read Magic as the first spell in his book. Then you roll one additional spell of the highest level your PC can cast for 2nd, 3rd, and 4th levels, rolling 1-40 on the First Level spell list in the Players Handbook (1D10 AND 1D4), and 1-24 for his two second level spells at 3rd and 4th level (1d12, 1d6). So all together you will have Read Magic plus one offensive, one defensive, and one miscellaneous first level spells at the start, plus one more 1st level spell for 2nd character level, one 2nd level spell for 3rd character level, and one final 2nd level spell for 4th character level. That gives your character a total of 5 first and 2 second level spells. This could give you a pretty random and useless selection of spells, but do it this way and see what you get. It could also give you a fantastic selection of spells. I'll make any adjustments that need to be made, so don't worry too much if you get sorry rolls. You can also try to start out with some scrolls, following the probabilities given in Appendix P of the DM Guide. Any scrolls that you have at the start can be used to copy the spell into your spellbook, but if you do that you will use up the scroll, of course.
Hit Points
Max at first level + Con bonus, if any, then roll for levels 2, 3, and 4, again adding any Con bonus that you are entitled to receive.
