The type ride is part of the training event - it's done at FSI or the training center for the assigned fleet. Type training can occur before or after indoc, depending on how the company decides to schedule your training.
The "reserve" schedule isn't quite like what you may be used to at the airlines. It's the name given to the schedule for the people who will have to be, well, "flexible" with their time. After you are off IOE, you'll likey be flying almost all of the days when you are on duty. With the "reserve" schedule, it simply means that you are on the hook for up to 18 days per month - you just don't know exactly what days are works day prior to the month in question. Even then, you might know only 4 "for sure" off days. The TA will require that people on the reserve schedule will have to call the evening before to find out if the next day is a duty, unless it's already a known day off.
There are limits, too, on the reserve schedule. Tours can only be up to 7 days long. After a 7-day tour, you'd have to have at least 4 days off. If the tour is 6 days or less, you'll have to have a minimum of 3 days off.
As Grizz said, part of the reason that new-hires are put on the reserve schedule is so that they can be put through training more quickly. After indoc and type training, there's a short company aircraft training program (classroom and at least one flight) followed by IOE. The company is apparently putting new-hires on the reserve schedule so that they can try to match up new-hires with available instructors and aircraft.
