Depending on what kind of area you look in, you might want to consider a condo, particularly in a new building. The buying and maintenance process is much easier than buying a stand alone house. Also, the process is not nearly as overwhelming as it may seem, maybe because I bought a condo, but after getting approved for a loan, the rest was a breeze compared to what I had expected.
I agree that you should have patience and a timeline (though if you are not pressed to move in anywhere, that is best) and shop around for your mortgage, your agent, and your property. When it comes to your realtor, you have to trust them. When it comes to your mortgage loan, un/fortunately your agent may be a dick, but as long as the rate is low and it's from a legit lender

Brokers have the most access to different loans and more likely to get you the best deal. I found a wonderful lending agent who I personally liked but he couldn't offer the same rate as this other guy who was always getting "sick" and not returning my emails on time. It was purely about numbers.
Become an expert, or as much of an expert as you can, in the areas you want to live. That just means go to a lot of open houses, speak with realtors, and homeowners if you can and look online. As an EP it won't be a challenge for you to chat people up and glean info from them.
When it comes to mortgage, get pre-approved and have that letter with you when you shop around. It will help immensely once you find a house you want to buy and realtors will take you more seriously.
I personally really enjoy real estate and even studied to become a realtor, so I had seen a lot of properties over the years helping friends househunt and also on rental hunts for myself, and then I went into high gear when I was ready to buy. So I had a very good idea of a fair price ranges for properties and when I stumbled upon a great deal, I took it.
After you've done all your preparation and you find "the one", jump on it immediately. Express interest and have your realtor draft an offer right away (after figuring out a good price) or put down the deposit to 'hold it' if it's a condo. The market in most places is still down so there is wiggle room. If they can't come down on price, you can ask for improvements/repairs to be done or money towards closing costs or even some of the furniture or window treatments to stay if you like them.
Find a realtor you trust who is experienced but don't sign a contract with them binding you to paying them even if you find a find a place on your own. Overestimate how much you will spend in total, cash, for closing, move-in, and first month's expenses, but get exact figures for your estimates. Like Spirilis said, find a good title company. Legally, you are not bound to a property's "preferred lender list" or title company.
And good luck! Exciting times! You will figure out your real "Must haves" and "dealbreakers" as you shop around and when you find "the one" for your first home, you will know!
