How to set up full access and limited access wireless networks to laptops

Question

Dear Apple,
I just received my Apple 1 TB Time Capsule. Can someone please help me with a network configuration I want to set up?
I have a cable modem, and, three computers: a G4 iMAC (system 10.5.5), an Apple MacBook (system 10.5.5), and, a PC laptop.
The Time Capsule is connect directly to the cable modem.
Regarding the computers:
(1) I want the G4 iMAC to connect directly, via an Ethernet cable, to the Time Capsule, WITH FULL ALLOWED ACCESS to the Time Capsule and to the back-up function of the Time Machine feature, and, with allowed access to my HP inkjet printer (class 6110);
(2) I also want the MacBook laptop to wirelessly link to the Time Capsule via the Airport utility on the laptop, and, WITH FULL ALLOWED ACCESS to the Time Capsule and to the back-up function of the Time Machine feature (using WPA/WPA2 security, and, without the network name visible to third parties), and, WITH allowed access to my HP inkjet printer (class 6110);
(3) I want the PC laptop to wirelessly link to the Time Capsule (using WEP security), but WITHOUT ACCESS to the Time Machine, WITHOUT access to the back-ups on the iMAC, WITHOUT access to the back-ups on the MacBook, and, WITHOUT access to the inkjet printer --- I only want the PC to use the Time Capsule as a WIRELESS ROUTER so that the PC laptop can access the internet.
(4) And, finally, I want to specify (Time-Capsule/Time-Machine/server ) access ONLY to the iMAC and the MacBook, so that others cannot gain any access.
I specifically need help to set up and configure the Time Capsule so that the PC laptop, as stated above, should have limited access to the Time Capsule --- namely, only to access the internet, and, not even be aware of stored data on the Time Capsule, not even be aware of the inkjet printer, and, not even see my WPA network name when the PC scans for wireless devices.
I also want the iMAC and the MacBook to have access to each other’s data stored on the Time Capsule (like a common server).
I have an old D-Link DI-624 wireless router that I used before buying the Time Capsule, which is available, if needed. Hopefully, I can configure the Time Capsule so that I would not need the old D-Link.
Thank you in advance,
David.

The basic method for remote access is not changed.

You have a few issues.
The really big one.. the school firewall should not let you connect to home.
Check the IT admin at your school but if they allow anything but a few protocols like http and https through, they are not doing their job. You cannot afford in a large network to have every Tom Dick and Harry access any open device.. that can introduce viruses and trojans into the network behind the firewall.
The general method for remote access on large networks is vpn and the TC offers no vpn connection.. just AFP.
If you intend using 3G wireless stick or the like then you can get access.
The next issue is static public IP or how to find the TC.. you need some way to find the IP if your ISP does not offer static ip, and the tc has no dyndns client. Since Apple shut down new users for mobileme and will close that service there is no method to find the TC IP without owning your own domain. You would be better placing the TC in bridge behind a router that does offer dyndns and port forward AFP (TCP 548) to it.
