*Edit. Go Today! It'll only be a great suit if they tailor it and it fits perfectly*
I am 6'3. I'm not 48"s but not far from it. I highly highly recommend Men's Wearhouse. You know the "You're going to like the way you look.. I gurantee it" Great suits, Good prices. Go today though, they'll need to tailor it to give it a good fit. Not sure if they can get it by Friday, but one thing about them is that they will always try. (Here at least, I've had excellent service at the one here in Knoxville, TN and the one in Atlanta when I lived there.)
The thing that's nice about Men's Wearhouse is that they are usually professional "dressers" I'm not saying they are top end great people but all they deal with every day is men just like your husband coming in and saying "I need a suit, Help!"
Shoes. I have 2 pairs. A Black set of Dockers that is really comfortable I spent about hmm $50 on? And a brown pair of Johnston & Murphy shoes that I paid around $130 for. If he's going to wear dress shoes every single day, I'd eventually invest in a nice pair of shoes. If they're just interview shoes, don't bother. By don't bother, I mean you can get away with a cheap pair. The different in expensive and cheap shoes typically is the ability for the leather not to break down over time.
I wear dress shoes every day so I wear my J&M's daily. Ask about polish/shine kits also. (Or just go buy one at Target) He will need one. I try to clean/polish mine every few weeks and once every year or so I take them to a shoe repair shop locally and have them "repaired" to fix nicks in the leather, etc. It's worth it to take care of nice shoes.
I wouldn't do Doc Martens if it were me, although I wear shoes like that all the time when no interviewing/conducting business. People do notice.
Check list Interview
Well pressed suit that FITS is the #1 thing. Any time the suit feels uncomfortable, go have it refitted. It's worth every penny to have it fit PERFECTLY.
Clean look. I would imagine this doesn't need to be said.
Shoes nice and shined.
Tie Tack, Get one and use it. Even if it's a cheap one. Tie needs to be sitting in place and the tie tack does that. Big guys like us have a tendency for the tie to be waving all around and just make us look like some "big guy dressed up"
I'm not talking about those cheesey Tux/Wedding Shoes. Just a nice pair of comfortable shoes. Oh and from experience, if they aren't comfortable day 1, don't expect them to break in like tennis shoes. Dress shoes have a tendency to have sharp edges for that "crisp" look. All it does is gives you blisters. You can get great shoes that are comfortable, Don't let someone tell you that they'll "Break in" Find a comfortable shoe. It's important. Also, grab one of those shoe horns and USE it. The shoes will be ruined within 6 months of forcing feet in and out of them if you don't. (especially with chaep shoes) They don't work like tennis shoes where they're designed to get that kind of "abuse"
Dry Clean your Suit! And use a heavy duty wooden hanger. The suit will ruin over time of sitting on a flimsy one. The suit should come with a nice hard plastic one that will work just fine, but if it doesn't.. Buy one at Bed Bath & Beyond for a couple of dollars. Again, it's worth it.
Just some examples.

I think these look great personally but they will look different on big guys like us. I have bought the Jones New York Brand and been happy with it.
Oh and your comment about "Too conservative" I don't know much about non conservative ones. When you're wearing a suit, it's to look formal and classy. Make your statements with your other clothes. I'm a t-shirt and shorts guy so I'm all about being comfortable and not dressing up for things.. When it comes to interviews, get the standard/classy look. It's important.
Oh, might as well buy charcoal color so it can be worn as a funeral/wedding/event suit as well.
