If i put my gigabit switch inside the router, I understand that the internet will always be slower, but if I transfer files between two computers capable of gigabit ethernet attached to my gigabit switch, will the fact that my 10/100 router is attached to the switch also slow down the transfer between the gigabet computers?

Simple answer is no. Routers work on layer 3 and also have a WAN side and LAN side. On your LAN side, which is your LAN switch (in your case it is the Gigabit LAN switch) you are probably running NATed IP addresses from DHCP server. It could be the router that's performing the DHCP server or another computer that's doing it. The router will NAT IP addresses that are local to the external IP address that's been assigned to you by your ISP.
Communications between local IP address ranges (layer 3), i.e. 192.160.x.x, will not pass through or even reach the router's LAN port as there is ARP protocol to find the MAC addresses (layer 2) within the LAN. This is done by first send out broadcast messages within the LAN side and then resolving which local IP address belongs with which MAC address. This is why if your make changes to your NATed IP address or change LAN ports there is a long time before things get through. When this happens, you should reset the LAN switch to force an ARP and also force the LAN switch to forget the MAC address spanning tree tables so that it is in broadcast mode.
So in summary, computers with GigE NIC attached to GigE switch will hum at rates faster than 100 Mbps. It will never reach anywhere near 1 Gbps unless all the computer on the LAN are using jumbo packets. Maybe as fast as 200 or 300 Mbps. There is also a latency turn around for each packet on the computers. Packets from computer that are destined to WAN, i.e. directed to the router will work at the rate of the external WAN link to your ISP, which will more than likely be a few megabits/sec.

It won't affect you lan that is connected to your gigabit router. The port that you connect your 10/100 to will auto adjust to match it's speed. The rest auto adjust to the gigabit speed.

On a network, it's always best to have all the hardware on the same transfer rate level, basically if u had a G router, and a B wireless card, the fact that the card is only B, the data wont transfer on a G speed, try bestbuy.com for a gigabit router!

Your switch will only slow down on the port that the router is connected to, which is your internet connection. I highly doubt that you have an internet connection of 100MBps or higher so it really wont affect anything.

in your network no.
you have wasted money on gigabit hardware when your network will never utilize all of that bandwidth
networks only run as fast as the data is being offered. so basically the hard drive is the bottle neck on most home networks. if your hard drive has a max sustained internal transfer rate of say 75 Mbs that is the fastest rate that your PC will ever transmit data at regardless of the network link.
more "bandwidth" does not always equate to a faster network
