Go to the link I will post and allow Crucial to scan your mac with their software. They will tell you exactly what you can install and what you will need. FYI, if possible buy as much ram as your iMac can use. 1 GB is not enough so get at least 2 GB if your iMac will run it.

Apple no longer sells a 24" iMac. The fastest 21.5" is $1,699 with a 2.8GHz Quad Core Intel Core i7 processor. The fastest 27" is $2,199 with the 3.4 GHz Quad Core Intel Core i7 processor.
The iMac uses an Intel Core 2 Duo processor which is a 64 bit processor.
Up to 4gb.
Purchase your ram from a reputable source such as Crucial. There is a plate on the bottom of your iMac screen. Remove that plate, which is held in place but 2 fillips screws, to gain access to the ram. Click the link to learn more.
IMac - Intel-based - was created in 2006.
CrossOver requires a Mac with an Intel Core Duo processor to replicate a Windows type computer. It will not work on a G5 iMac.
Yes, you can upgrade to Lion from any iMac that uses the Intel processor. But the newest OS is Mountain Lion.
The iMac does video editing better than any Windows PC.
Depends on what year and what particular model. A new iMac base model comes with an Intel 2.5 GHz Quad Core i5 processor.
No. An iMac G3 and a standard PC have totally different architectures. There is no way to physically install a Core 2 Duo. Even if you could, the chipset and firmware are incompatible.
To add an additional 1GB to an iMac to give it 2GB of RAM should not cost more than £15 (US $20). The Intel based iMacs are very easy to upgrade via the access door on the bottom. (See links below)
