Well, there's quite a bit of information out there, and congratulations on taking this next step.
By all means, do your research, pick your winners, put your money down, see how it goes.
Many many people have gotten crazy rich doing just this. Most do not. I sincerely hope you do well and make bajillions of dollars. If you remember these well wishes and want to make a donation upon hitting it big, I do accept paypal, checks, and blocks of gold delivered to my door.
Somewhere on this forum someone has a quote that goes like "the best thing that can happen to a noobie stock investor is to suffer a major loss in their first few years."
I hope you never have a big loss, but I also hope that if you do, it comes soon, while you have a chance to shrug it off and figure out something from it.
Don't be afraid to invest and try things out, it
is only money. I have picked a couple stocks too, just in case I'm a stock picking genius. So far...still gotta go to work every day, but they aren't doing too badly. I mean, they've lost close to 25% of their value, but I'm still hopeful!
As for the tax advantages of deferred-taxes.
Not all of your income in retirement is going to be subject to tax. So even if you want to have "100k in income" it won't be anywhere close to 100k in taxable income per the IRS. Some of it will be long-term capital gains. Some of it will be dividends...which are taxed like long term capital gains, sometimes?, and there will be years where you are living a little off of principle.
Unless you work a really really long time, and have no savings outside of retirement accounts, and have awesome returns within those retirement accounts, you'll pay less taxes before and after retirement by using the traditional IRA and 401k. Like 99% of folks are going to be better off going this route.
You need to run the actual numbers yourself for your actual situation, but it will surprise you.
http://www.madfientist.com/traditional-ira-vs-roth-ira/Your argument is: I'm going to pay the taxes eventually, so why not pay them now? That way I have an account that will never be taxed again.
The counter is: If you're concerned about future tax changes increasing your burden, just know, a tax code change created the Roth IRA, and a tax code change could take it teh fux away. Also, Once you pay that money in taxes, it is gone
forever. You
might have to pay it in the future. But you might not also. And then what others said, you're saving a dollar taxed at 28% for every dollar you contribute. But the first seventy thousand or so you withdraw every year are taxed at less than 28%. Some aren't taxed at all. It is real, tangible, ROI. As close to a sure thing in investing as you'll ever get. A 28% ROI+ on even some of your money...no brainer.
Good luck to you!
