HP, the above address here on CC of course, will answer any questions you may have on a CR! Parts are slim but everything you mentioned can be had at the listed location-including suppliers and part numbers.
Now, if you want to almost eliminate a CR's learning curve totally, grab a qt. of your favorite beverage, find a comfortable seat, set aside an hour or more and read the entire thread on "the other Ed's build...." by Cpteddie. It WILL / CAN save yours hours of time, frustration and of course money!
And may I be the first to welcome you to CC? Welcome!
