Eyes are an aesthetic choice made by the maker. Although you do see a lot of them, it doesn't necessarily have anything to do with the quality of the bow, or the frog. Several modern makers, some of which produce extremely high quality bows, prefer not to use them.
Likewise, the tip of the bow is missing a tip-tip, or the small little bit of ebony and/or ivory that protects the beak of the bow. I agree that it should be replaced, but it looks like given the thickness of the ebony that is there now, a decision was made to use just ebony instead of ebony and ivory/bone/silver/plastic/some other tip material.
I am definitely in the rehair/repair instead of replace camp. Pernambuco, and Ebony are indisputably in short supply, and the "throw it out and start over again" mentality that is applied to so many other areas of our lives now is one that is very dangerous to play with endangered natural resources. Is it possible to bring the hair on the bow to tension and play some longtones on it? Old hair will not give you a sense of the attack or response of the bow, but can still give you an idea what it could sound like.
Talk to your repair shop, and see if the cost they quoted you includes the rehair (new tips often do, as you have to remove the hair to do them anyway) and talk to them about the material they plan on using. Mammoth ivory, especially large enough for a bass tip is quite expensive, as are some of the other options, but if you like the look of the Ebony that is on there, that is an option, and the material involved is not as expensive. Tips are time consuming, and matching them to the head without damaging it is not an easy skill to master. Your repair shop might come back with a cheaper option when it comes to tip materials, but that is a pretty standard rate for that repair.
