Looking for a JOB

This is my final simester of my BA and that means that it is time to start looking for a job!!!
Where to start from? What kind of job do i want? How much money to ask for? These are all questions that are sitting in the minds of all my class mates.  Unlike most of my class mates i have work experience in the field that i want to find a job in, but this does not mean i can have any job i want.
For the last couple of weeks i have been in and out of dozens of internet sites looking for different jobs that i might want to do.I could easily stay at my current job where everything is nice and cozy but i would be cheating myself.  I want to working in a new field that i dont have any experience in and so i feel like all my other class mates.  Every job opening i see requires experience for that particular job.  How am i supposed to get experience in a certain field if in order to get a job i need experience.  It is a "Catch 22". 
So i have sent out around 20 resumes and signed up for about 5 different job web sites and i am hoping to start getting some telephone calls back.  Other than that i have also filled out forms on various government web sites applying for certain jobs. 
I am very lucky that i worked for two years at a real company and had a real job before starting school.  I hear all my classmates talking and see how difficult it is to get even the smallest amount of work experience.  I know that it will be hard for me to change fields but at least i know that i can get a good job in the field that i have 5 years experience in.
The big question is how much money to ask for.  This was a big problem for me when i first started going on job interviews right after the army.  I would always get to that point in the interview and have a small internal panic attack.  Now that i am starting this process over again it brings back all those memories.  At the job i had before i started school i was making X amount each month.  Now when i go to an interview and they ask me what are my expectations for salary i want to say X+4000.  I obviously dont want to make the same as i did before school and i for sure do not want to make less.  I need to somehow convey to the new company that i now have 5 years experience (2 years full time and 3 years part time) and i also have a degree for the university.  But i also know that if i want to start in a new field that i might have to take a pay cut in the first year or two.
So these are all dilemma that i have to deal with while i am looking for a job. And on top of all of that i have to consider staying at my current job where i am very happy and enjoy my work.
So wish me luck on my hunt and if you hear of any good jobs please let me know.
Bye for now :-)
