Second it has Shimano tourney center pull brakes. They are in pretty good shape and work OK, but I need to replace the levers. Are there current shimano levers I can use with this type of brake?
Any help would be greatly appreciated.

The Lark and Thunderbird derailleurs were cheap stuff for their era- I would be willing to bet that replacing them with Shimano Altus or Sora parts will work without issue. You might run into a problem with the old chain and new derailleur- chains have gotten a little narrower over the years, but an "8-speed" chain will work on the current freewheel without issue. It won't be index shifting, but I think indexing is oversold anyway.
Any current "road" brake lever will work with your centerpull brakes. Here's a good, basic set:

Here's the corresponding Shimano set:
