Welcome to the Phorum Matthew!
Lots of people who can help you through your restoration here! How much do you know about electricity, taking voltage and resistance measurements and what equipment do you have?
A good first read is Phil Nelson's "Beginners" topic.
Second, there is a good copy of the Service Bulletin for your model at the Audiophool site. You will need the Djvu reader to view it but he has links to the reader download on his websites. If you can't make it work, post here and I can convert it to PDF for you.
Read through some of the electronic and cabinet restoration threads on this phorum to get a feel for what people do and how they go about it. Explore the Tech Section to see what information is available. Your model is a 1948 model and thus more "modern" than some of the older Philcos but still well in the range of many of the restorations that people do on this phorum.
You will need some basic skills and equipment. A decent volt/ohm meter and soldering iron (I use a simple 40 watt pencil iron and I have a larger iron for some times when 40 just won't heat up a connection -- usually something connected directly to the chassis). A signal generator will come in handy for troubleshooting and aligning the radio after you finish recapping. In your case, your radio does not have a power transformer in it so I would emphatically recommend you get an isolation transformer to use between you house power and the radio while you are working on it on your bench for any energized testing (for and example of one see: http://www.ebay.com/itm/Vintage-VIZ-Isot...Ciid%253A1
As you'll read in the Beginners notes, you will be recapping the radio by replacing all the paper and electrolytic capacitors with new ones. Some people stuff the new ones inside the old ones, others simply replace them. You will want to check the value of the resistors as you go along and replace any of those that are more than 20% out of specification. In some cases, to make those measurements, you will need to unsolder one end of the resistor to ensure you are only measuring the resistor and not some other electrical path in the radio.
A tube tester is nice but if you are not going to get into this sport in a larger way then not necessary right away. You can check the filaments in the tubes with an ohm meter and then see if the set works after you get it all recapped. by checking voltages in the set you may be able to track down weak or bad tubes or you can get some replacement tubes and swap them out to see if it works.
Enjoy!
