How many processes & RAM I should assign to my SharePoint VM development environment

1. 32 GB RAM
2. Core i7 with 8 processes.
3. 670 GB hard disk.
4. Windows 7 professional.
5. Inside the machine I installed VM workstation 9.0 .

And I have defined the following specification for the VM:-

1. 24 GB of RAM
2. 4 processes.
3. 80 GB of hard disk
4. I install SharePoint 2013 server , SQL server 2008 r2 sp2 , visual studio 2013, and TFS.

Currently the VM is working well, but I have the following question about my setup:-

1. Will it cause any problem if I assign all the available 8 processes to the VM instead of 4.
2. Will it cause any problem if I assign the available 32 RAM to the VM instead of 24 GB.
3. I have changed the number of processes assigned to the VM from 1(default) to 4 , but I am unable to changed it again to 1 processes (if I need in the future)?

Thanks
