Tradestation up-sells needed or not?

[borderfox100]

I have just got my Tradestation account opened. However, I was about to sign off on some small print and they had automatically added a couple of features;

- Tradestation Portfolio Maestro
- Radar Screen


These account for a monthly subscription of $126/month. Although they had selected them for me automatically, I can go back in and untick them. Anyone familiar with these tools? Do I need them? Seems damned expensive!
