Your weapons are bad. But don't worry- play a while in the DZ and you'll get much better equipment. Of course, the DZ is also made for playing *with* other people. Going solo always makes it more difficult (and less fun, imo).
The DZ is also level locked- if you reach level x, you will automatically connect to the next higher DZ instance, and so on.
If you see some extraction point as "blocked", you might want to move to a different one. There are quite a few around (I think at least two per sector).
