Congratulations on the new boat, assuming the survey goes well. Assuming you are handy and just not experienced, you will pick up everything you need to know in time. You should be there for the survey and learn from the surveyor what you should focus on, whether they are items that impact the sale or not.
Thanks to our own MaineSail, who regularly posts here, you should bookmark this following website. It is extremely good at showing you how to do many of the basics, including rebedding the hardware. However, you don't necessarily have to fill and redrill every hole. It depends on condition and whether they are already bed properly. Get used to every project taking twice as long and costing twice as much as you expect and you'll stay sane. Have fun. Many love the satisfaction of working on their boats.
