Welcome to the forum and let me see what I can do to help you with some of your problems.
Firstly knowing what OS you are running...
Click the start icon, then right click on the "My Computer" and you should see an option called "Properties". This should tell you Basic information about your computer. Windows version is under there... mine is windows 7 and windows XP on another I have.
Under the system section you will see information about the system type... 64 bit or 32 bit.... NOTE if you are running a 64bit OS you can usually still use the 32 bit versions of the coin clients (just some parts will not run as efficiently as they can be i believe)
Ok so now slight promotion of another OS for you to just go for it and try as you will find certain advantages and if you can get set up mining then you can have a play at a Linux OS.
I would say try Ubuntu 12.04, its free download, and can be installed alongside your current windows instalation, or you can even install it on a USB and boot from USB each time! If you have used a mac before the you will find similar unix feature... though my mac experience is less so I can't really comment here, but give it a try, you will find LOTS of online help for any issues you have with it, and being on a linux u will find you can build from source the clients of PPC or any of them very easily and any other software you get source code for.
So with this information you should be able to download the appropriate client and mining software. From what you say you have the client downloaded, blockchain fully downloaded and connected to the network correct?
You should have been prompted to create a ppcoin.conf file if I remember correctly have you done this? In there you will need to have set a Username and a rpcpassword, these are your values that you will need to set in the miner if you are looking to solo mine PPC.
Ok so any kind of mining hardware will need software to run and mine. There are a few out there developed by the bitcoin community that work perfectly well and are constantly being updated as the mining hareware changes as well. Some of your choices are:
CGMiner - My personal favourite,
BFGMiner - Downloaded this but not used it yet
GUI Miner - This is what I started on, as it has a nice GUI, the rest are command line interfaces... once the miner is set up and mining you get more information I find with the command line interfaces.
I feel I should stop here and ask you a few questions about your mining setup as the difficulty of PPC mining is such that unless you have some serious mining hardward you should not attempt to solo mine. You should pool mine so that you get something for your electricity and time.
If you are asking these sort of questions as well, no offence but I would not expect you to have a $30,000 mining rig from BFL which might be worth trying to solo PPC, everything else stick with a pool. However EVERYONE mining should set their miners to have a last resort to solo mine PPC in case all the pools get attacked, though this is less of a necessity with PPC thanks to its superior design of POS mining also securing the network
But do you have an ASIC? have you a GPU you wanted to try mining on? is this an experiment for you or have you invested money in hardware already?
Hope this helps ease some of your frustrations, don't worry we've all been there
