I am not sure if you can get any PMP exam practice portals where you can customized so many things (your point 2). I have few recommendations based on my experience:

1. Rita Fast Track: You can take exam questions based on knowledge areas and also choose high complex questions (super PMP). This will require installation on your Laptop.

2. www.pmzest.com: You can design tests of 100Q sets or 200Q sets. However they only provide mix type questions (mock test only). This is web based.

3. www.oliverlehmann.com and www.pmzilla.com is paper based tests.

I passed PMP exam around an year before, you might find my LL useful: http://www.pmzilla.com/cracked-pmp-exam
