First off, most guys in the gym are not built like the hulk. There is no reason to be nervous in there. Also, most gyms have programs that aren't advertised, but are significantly cheaper than the ones that they do advertise. These programs usually only allow you access certain days and times of the week rather than unlimited access, but they are definately affordable.
As far as keeping weight on, you need to eat a ton of high quality and high calorie foods. You should eat throughout the day and not just during meal times. I recommend having several protien shakes a day. Running and Cycling, while good for your cardiovascular health, will not help you to keep or put on weight. In order to put on muscle, it is critical that you do weight training exercises. At home, without weights, you can do things like squats and lunges for your legs and push ups and pull ups for your upper body. Also make sure you give your muslces time to heal before working them again or your growth will be substancially slowed.
