^^ DJ is obviously right, but a few basic things I'd suggest/point out are:
• Shimano and SRAM wheels are compatible.
• Shifters are the most expensive parts so factor the replacements.
• Generally it's my understanding that the shifters and cassette are what needs to be compatible. Most front and rear road mechs will work with each other from the same manufacture.
• Gearing is personal, but I'd start with a compact crankset and a 11-25t or 27t. 9 speed shimano cassttes are fairly cheap, but you can now get Tigra 10 speed so don't that be a decision-maker.
Other than that all the usual rules about measuring apply and ultimately just cracking on will highlight what you don't know.
