My husband and I will have our contribution percentage maxed out on our 401k soon, but would like to do some additional saving for retirement. We are young, and just got into this, so we don't know all of the rules. So, I need some help.First, we have an IRA which resulted from a Master Retirement Plan and 401k rollover. I was wondering if we added to this if we could deduct the money from our taxes. I didn't know if we could deduct this if we were already contributing to a 401k.Also, we were thinking about opening a Roth IRA. My husband is the only one working. Since I don't have an income, can we only contribute $2000 a year, or can we contribute $4000. I've also heard that you can only contribute to a Roth or a traditional, but not both.My husbands work also puts away SEP funds for him. I know that we had to open a brokerage account for these and that we handle them, but I didn't know if we could add to these, or if they had to be kept separate. I don't even know how the taxes work on these.My last question has to do with our son. He is all of 8 months old, but we would really like to start putting some money away for him. I looked up things on Educational IRAs, but the contributions are very limited, and it makes it so you can't take advantage of the Hope Scholarship or Lifetime Learning Credits. It also has a lot of stipulations that I am not sure if I am willing to deal with. Are there any great suggestions for saving for a college education?Thanks in advance for all of your help.
