Braveheart gave good advice both on saving your raise and disability insurance. I try to increase my 401k the size of my raise, if possible. All you do is mutliply the raise by the avg hours worked per week, add that to your avg weekly gross and then calculate the percentage increase in your avg weekly take home and increase your deferral by that number. A $.35 raise would probably equate to a 1-2% bump.
Disability insurance is a must, IMO. I have Combined and, no, I do not work for Combined part-time, although you may think otherwise from my previous posts on this subject. I have accident and sickness policies and are covered 24/7 for about $100/month. Payments for work related injuries are in addition to any workers comp payments. Payments for all ER visits are $300 and are in addition to whatever the insurance pays.
Plan now while your income is steady for retirement. Social Security should be viewed as supplemental at best.
