A prospective Teres owner with questions

The Cult Of The Teres has nearly convinced me to take a chance with a basic Teres -- the 150 TT. BUT, I figured you guys could, as the Cowardly Lion says after declaring his intent to rescue Dorothy, talk me OUT of it. Um, I mean, into it...Well, you know what I mean...

I've developed some nerve damage in my hands, so DIYs aren't the best route for me. However, TWL, who seems revered on this site, has the OL Silver tonearm (mine is on the way), and probably has the same model as I'm considering buying. Despite the fact that I have no clue as to whether or not TWL is secretly an axe murderer, his take on turntables is quite knowledgeable, so who am I to buck the masses?
Onward to the questions...

1)Saying a setup is simple is easy to say, but quivering hands might make a mistake. Is there anything that could break during setup?
2) I will, of course, tell Chris, at the time of my order that I'm also getting a VTA adjustor with the tonearm. Will that make the "drilling" any more complicated?
3)The sonics. (And yes, I can ask Chris, but there's only one of him and a million of you ["...it takes a village...]about this.)How is the Teres at retrieving very, very low level details such as side/back walls (aha! The infamous "imaging/soundstaging freak rears his head!)ambience retrieval and soundstage HEIGHT.
Lastly, is it warm -- or even overly warm in the midbass region? I've owned a Versa Dynamics 2.3 for years, but it's back in California waiting to be shipped to John Bicht for repair(John expects a 4-6 month wait; it's not his main profession anymore, and he has to squeeeeeeeze it in), so I'm buying another turntable to live with given that I just bought a Microgroove Plus last week -- along with the Silver tonearm. I have a Rega 3 that I gave my sister right here in Connecticut. I'm accustomed to the Versa's depiction of music, but it's not a warm turntable at all. So, I want to be prepared in case the Teres is warm, or dark [dont' like a "dark" sound very much].
For all the rest of the turntables traits, I trust you guys' take on it. I've only been reading the entire Teres threads for the last 36 hours (it's VERY, VERY, VERY cold here in the Northeast today). NOBODY is going outside who doesn't want frostbite. That gives me time to become positively neurotically compulsive/obsessive about this turntable....and you're all invited to observe...
Okay, I'm waiting -- and wanting -- to be (completely)converted. Help me out here, gentlemen (and ladies).
