I'd suggest investing in something like Microsoft Money or Quicken. It'll give you an easy way to set up budgets and track your income and spending. If you have a decent bank they should support MS Money.
Personally, I use MS Money, it does everything I need it to: income/spending tracking, check balancing, budgeting, taxes, bill tracking and reminders, investment portfolio, 401K, stock and information portal, et al.
Then again, this can all be done for free or relatively cheaper by other methods. I prefer this way because everything is centralized.
