Need home buying tips, any agents here, or anyone with buying experience? Long

So, I have a couple questions, but I'll give you the situation first so you know whats going on. We have only bought one home, 27 years ago, and bought straight from the owner. So we have like no experience with agents.

A little over a year from know we will be moving from Lyons, CO to Lakeview Oregon. Moving from a small town surrounded my big towns, to a small town surround by nothing!

Anyway, last time we were up there we hooked up with a local real estate agent that a friend recommended. We didn't sign anything, but she was suppose to be keeping an eye out for what we wanted. Planning on buying when we find what we like, even if not moving for a while.
So I've been watching Zillow, and Realtor.com almost every day. We found a house that we think is perfect, everything we want, and in very nice condition. So about a week from now, I'm flying to Reno, renting a car and driving 4 hours north to Lakeview, just to look at this place. We called our agent in Lakeview, and turns out the house is one of her listings.

So, question 1. Is it a problem with her acting as both the sellers agent, and the buyers agent? Or do we need to hire a buyers agent to act as a go between. I mean, her acting as the sellers agent, she wants to get the most she can for the sellers, and her commission.

Question 2. I think I have her talked out of this, but my wife wants to give them a low ball offer, hoping that they will haggle and come down off their asking price. I was doing some reading on-line and think the only time its ok to lowball, is if the house needs work, or hasn't been well kept. This particular house is in excellent shape, has everything we want, and is basically my dream place. So also from reading online, I read that if the home is everything you want, you should be prepared to offer the asking price or more.

To further complicate things, Lakeview is experience a temporary high in housing prices, do to a company building a new biofuel plant on the edge of town. Hundreds of people have moved there, buying up all the houses, and driving the prices up. In about a year when the bio plant is finished, most of these people will leave and only 75 or so will stay to run the plant. Our agent is expecting the housing prices to drop back down to normal (cheap) lakeview prices after this all happens. So, we're kinda buying at the height of an artificial housing boom, and might end up with a price that sounds reasonable to us, but in a couple years the house might be worth significantly less that what we paid.

Any advice ?
To answer question #1, it's absolutely legal for an agent to act in this manor. But, it's also worth the few dollars to hire an attorney to go over the paperwork. This could save you a ton later on should he find some type of deed restriction or other abnormality you wouldn't expect.
My BIL is a real estate agent, and if I've learned nothing from him, its regardless of who has the listing, he represents only one person, himself. He's not alone.
Question #2, it's not a crime to offer less. It doesn't mean they're going to take the offer, but they may counter and go from there. Every home I've bought, I started $25K or more under asking. Do some research, find out how long the house has been on the market. The longer, the more likely the seller is to come down. Having financing in place and ready to go also helps. That pre-approval letter is key to make that work to your advantage, especially if they've already dealt with a prior sale falling through.
If the seller isn't willing to come down on asking, then insist on their paying all closing costs.

Having the well tested is a wonderful idea. I would also have the septic inspected as well.
Every home I've bought, I've had the seller pay for any inspection and testing fees, with the understanding that they will be reimbursed if the home passes inspection. That saved me a ton on asbestos remediation other problems of a rental home I was considering.
Another thing you should do to avoid future aggravation,
go to the property, pull out your cell phone and see what the service is like. Research the cable TV and internet service and speeds.
Also, have a survey performed. Avoid any property line disputes that pop up later on.
