four_engines:1. How much should I set aside for my accomodation if I wish to stay in a 3 star hotel?
This very much depends. You should book the hotel through the tour operator becasue then prices are much lower...
four_engines:2. Any nice hotel to recommend? Budget is about USD 60 per night.
60$ per person or per double room? It should be enough but - see the answer to the first question
four_engines:3. What is a reasonable price to pay for 1 day of say 3 dives?
normally they offer 2 dives per day. the price is between 50 - 70 $ for 2 dives
four_engines:4. Which are the best dive sites from Sharm?
Tiran islands, Ras Mohammad - these are top of the top
four_engines:5. What is the modus operandi of the dive operators there? Do they pick you up from the hotel if it's in Naama Bay? Do the dive boats have warm showers?
Yes, diving centres are picking their guest although with the hotel in Naama this may be a problem because cars are not allow to enter Naama so the procedure is that you will have to walk to Peace Road (the main street) and being picked up from there.
They don't have warm water showers on boats. Some boats have cold sweet water showers
four_engines:6. I'm going there in April so what's the water temperature and how thick a wet suit should I be wearing?
5mm is asolutly enough - at the end of April water temperature is around 26 - 28 Centigrades
four_engines:7. Are 3-4 days enough for Sharm? I've got a total of 9 days in Egypt. Suggested itinerary is always welcomed!
Well - for me it's not enough. But you can have one day trip to Tiran, then the second day trip to Ras Mohammad, third day some of the local dives (Temple, Far Garden are the best). Then I would move to Cairo, visit their museum and go to Gaza - another 3 - 4 days. Or go to Luxor and Hurghada - and then one more day of diving in Hurghada - Giftuns are obligatory
four_engines:8. And of course, any dive operators to recommend?
Well there are plenty of them but most of us reccomend Camel diving centre, Blue Sea, emporers - you have to search the threads
four_engines:And, if there's any other information that may be useful, let me know too!
