Using resistors before the transistor is generally a bad thing because it adds noise.If you can do the matching with open stubs it will have a better NF performance. You always need to use dc block and rf chokes it's just the matter of if you are gonna use a stripline design(which are made in higher frequencies) or a discrete elements(for 2.4 any smd component will do 603,402,1206 etc).Because if you don't use rf choke your rf signal will leak down from the bypass capacitors. Same goes for dc block if you don't use dc block instead of going down from source to drain it will just move along the rf line.
