North Brunswick To Newark Penn (New Brunswick: to rent, vs, buses)

[techieguy]

Hello--
Looking to rent at Renaissance Glen ...
Does anyone commute from North Brunswick on NJT Northeast corridor ???
I want to get your experience on the commute. I'd like to know

1. How's the parking situation at Jersey Ave or New Brunswick ?
2. Express trains vs local trains from jersey ave or new brunswick.
3. any buses or shuttle that go from renaissance glen to Jersey ave or new brunswick.
4. Seating availability on the train.

Thanks in advance
