1) Congragulations on your upcoming surgery. I hope all goes well and wish you the best with it. There's is not one person here who will ridicule you and if someone does I or someone else will have something to say to them and it won't be pretty. Pushups are a great exercise but no, doing all those pushups won't give you a massive chest. At this point you are working on endurance not hypertrophy. You have to increase the challenge in some way.
2. I feel that you definitely need to put on some muscle. Showing abs is about having a low enough bf% but it looks like if you try to "cut" anymore your just going to be dropping muscle also and that will make it harder in the long run to ever drop that stubborn fat.
3. It is true that your body might have a certain set-point but it is certainly not out of your control. It is possible to undo some of that and sort of re-set your body. It won't happen overnight. The term endomorph is not a very good term. The reason is is that if someone looked at your pictures right now without any info from you they would not label you and endomorph. It doesn't really take into account body structure very well, but even given that you don't have the build of an endomorph. It's more like you are a slim guy who just had a lot of fat on from the looks of it and your body structure seems more like that of the ectomorph. But I think the terms are nothing more than a way for people to make excuses or discourgage themselves. Drop the labels and work on being who you want to be. In general I think that the ecto, meso, endo bodytyping thing is somewhat worthless as a way to predict long term outcome.
6) Dude, right now you a skinny guy with a gut and some gyno. You don't need cell-tech.
7) Diet is not something I like to get into since there are other much better than me at it. I feel you should lift heavy and gain mass. Focus on full-body compound movements. Not specific body parts. Do lots of lower body and back.
Welcome and good luck. Once you become addicted to iron you'll find everything coming into perspective
