Coming home was a nightmare - all uphill with a strong headwind and unable to change gear so I ended up walking most of the 2 1/2 miles or so home. Also my brakes now need adjusting and the little sensors for my bike computer are catching each other so I had to disconnect it.
Downtube friction shifters are very easy to work on. I'm not quite sure from your description what the LBS guy did, but here are some things to check:
1) The lever is tightened onto the lever bosses with a thumb screw (sometimes it's a real screw that requires a screwdriver, but usually it's a folding wire loop or something that will turn by hand). Did he simply tighten the lever so tight that you can't move the lever when you try to shift? If that's the case, just loosen the thumb screw until the lever moves easily but stays where you put it.
2) The cable tension should be just taught when the derailleur is shifted onto the smallest cog and the levers are flat against the downtube. Making the cable too tight may prevent you from reaching smallest sprocket. If on the rear derailleur, you'd have trouble shifting into the smallest cog - highest gear but should be able to reach all or most of the larger cogs - smaller gears. If on the front derailleur, you may be stuck in the large chainring.
In what way are your brakes out of adjustment? Too tight so they are scraping the rim? Or off-center?
Oil is good, grease is better.
