Yes.
North America is classed as region 1 for DVD, Bluray and games coding. The codes are there specifically to prevent discs from one region being used in another. Region 2 covers Europe. There have been a handful of DVD players that did not check the region code and would play discs from any region. Bluray players appear to be far more tightly controlled and it is very unlikely that any commercially available player will allow the coding to be bypassed. It is possible that players can be modified to remove the coding restrictions but these are unofficial modifications, void warranties and cannot be guaranteed to work continuously. As frustrating as the region coding is, the easiest and lowest cost route to take is to buy discs intended for use on your own player. Note that as the region coding is a commercial protection, non commercial DVD and Bluray discs do not have the code and can be handled by any player. That is subject to the player and the television handling European 50Hz content. The US normally uses 60Hz video so there is still no guarantee that your specific setup will work. It's a case of studying the manuals to make sure.
Commercial DVDs, Bluray discs and game discs are normally given a region code. The code is specifically to control where the content can be used. North American discs have region code 1 and use 59.94Hz refresh rate. Indian DVD players will normally be coded with region 5 so they are unlikely to play US discs, unless they have had their region codes removed. Also, India uses 50Hz refresh rate so some equipment may not handle North American content even if the codes do not conflict. With the right combination of disc and player, it may well work but it is not guaranteed.

No. You need a BluRay player that specifically says it can read 3-D disks
A region 1 DVD is intended to be used in North America. Any BluRay player purchased in North America should play the disc. Bluray players from other regions such as Europe will be expecting to play discs marked with a different region code so are unlikely to pay a region 1 DVD.
No, it will not play Bluray discs, but it is upscaling, so you can watch your regular DVDs at HD quality.
