For example:

require 'net/http'
uri = URI('http://example.com/some_path?query=string')

Net::HTTP.start(uri.host, uri.port) do |http|
  request = Net::HTTP::Get.new uri

  response = http.request request # Net::HTTPResponse object
end

What is the correct/rubist way to get rid of Net::HTTP ? i.e. HTTP::Get.new() or just Get.new()

If you want to shorten these, you can just import that namespace:

Net::HTTP.start(...)

include Net
# HTTP.start(...)

Be careful when you import aggressively as it might cause conflict within your class if you get carried away.

An alternative is to create aliases:

HTTP = Net::HTTP
Get = Net::HTTP::Get

The "correct" way is to just spell it out and not get too flustered by that. A typical Ruby program will bury this sort of low-level behavior beneath an abstraction layer so it's rarely a big deal.
