If you buy shocks which have adjustable seats/coil overs you wont need spring compressors - Good socket set should see it done and it's about a 20-30min per corner job - having said that if you don't have a garage/paved area abd havn't done anything similar before get someone else to do it for you - far less hassle
NB if you do it yourself when you take the old strut out make sure the driveshafts DO NOT fall out having someone or something standing by to hold them whilst you position new shock
