Tip #1 - If you do open a bank account for the business, which is a great idea, when they offer bank cards
leave them at home --- I was part of a new business venture while at uni and on too many occasions (mainly drunken nights out) it was too easy to extract money and spend it
Tip #2 - Don't forget to ENJOY YOUR UNI LIFE, don't let the business over take your next few years. I'd love to be back at uni again, they were fabulous years before then hitting the world of work work work..
Following on from babyboy808's post the DCEB seem to be offering to very good courses, at a good low cost -- worth a visit

Tip #3 - Setting up a business is exciting but it's not always straight forward (so much to consider) and with only limited time available in the day (inbetween uni or jobs), sometimes that is not enough!
When JSWeb was setup we also had full time jobs and it was a rush home each evening "from a proper income job" to answer calls which were left during the day and to get work completed. I remember lots of walking about of the office during the day to make calls and when I got home eating dinenr at the PC..and don't even start me talking about "essential" late nights...lol
But in the end it can all pay off and (I'm sure you will read this over and over again from other businesses) taking the jump from full time jobs to our own business was the best thing we ever did.
That said, you are at uni so unless you are a Richard Branson don't jump out of that!! Perhaps if you have some good skills to offer working under your own business name, as a freelance would be more suitable? This would allow you to earn money but also work around your availability e.g. When we are busy we are often on the look out for resources on a project-by-project basis. Two of our new full time team member were often working for us while they were at uni (project-by-project). We accomodated them when they needed to get their heads down to studying and partying but sinse they have completed uni life, they now join with us (which I hope they enjoy -- I must ask them
See example sites like:
www.iFreelance.com which allow you to post your services.
So enjoy yourself while at uni and good luck.
