I think bpp gave some good advice on this one.
Regarding newsletters--I don't think you should bother with them, for two reasons:
1) On average, their recomendatons do no better than the market as a whole. Sure, SOME claim to be better, or can show charts sindicating some of their portfolios have done well historically. But, you can't tell how many other portfolios the've had over the years and have quietly abandoned, etc. There's very little evidence that newsletters are, on the whole, worth a nickel. But, many people swear allegiance to various newsletters and feel they really have the inside track.
2) You don't sound like you have enough time to wait breathlessly for the next hot tip the newsletter would crank out, then act on it. You have other things on your plate right now, and probably will have for some time.
So, this would not be a good time to take on a new hobby.
I'd recommend that you invest in an appropriate Vanguard Target Retirement Fund. Your investements will be simplified, your costs will be very low, your returns will be far better than most individual investors get, and you'll have time to read more and learn about investing--if that's something that interests you. Then you can get fancy or tilt the allocations a little. In the meantime your money will be in a safe and sane allocation and you won't be lining some broker/advisor's pockets with funds you can't afford to give away.
Everyone has their favorite books, look around on this site and you'll find many good recommendations. My recommendation would be Willliam Bernstein's book "The Four Pillars of Investing." I think this is a superb starter book, it is readable and helps people to avoid the most costly mistakes many investors make. The table of contents, introduction, and Chapter 1 can be read for free at this web site. The web site itself has a treasure of articles written by Bernstein--well researched, interesting if you like statistics.
Best of luck! Whatever you decide to do, there are folks here to help out.
