Remington 700 accesories?

okay im getting a remington 700 varmint ive just found out about all the accesories available for this rifle i heard u can change it to clip fed is that true? where can i find the conversion? and im gettinga boyds thumbhole stock is this a good stock? it seems pretty but will it affect my accuracy? also what scope would u put on this id like around a 4-14 power but will use a 3x9 but im not good at picking scopes and the scope will need to cost around 300$ also whats the best after market trigger? id like one thats easy to adjust and simple to drop in and please tell me of other accesories that are good or just plain cool for it
