Can I add my experiences in the hope it may give some inspiration.
I originally had an electric guitar some 40 odd years ago, it was best described as cheap and nasty - although I thought it was great. I picked up the guitar again about a year ago after some 30 odd years away and although I have nowhere near the experience and expertise of others on this forum you may find my observations of some use.
I purchased my electric guitar via Marketplace on Facebook, it strikes me that there are a lot of second hand guitars and amps for sale (possibly because a lot of people give up very quickly?). My electric is an Epiphone Les Paul Studio for which I paid £100,I bought it mainly because it looks good, however the bonus is that it plays nice too. I got a local guitar tech to give it a once over and he said that I'd made a good a good purchase.
What have I learnt from my own experiences?
Give a local guitar tech a call, they maybe able to advise or possibly even be able to supply you with a suitable set up, secondly it may be worth finding any local groups of musicians who get together for jam sessions to speak to. I am very lucky in that I have both very local a group and guitar tech near to me, which is very useful as the nearest decent music shop is now more than an hour away from me.
Another thing I have been looking at recently is a series of videos released by Andertons music in Guildford (I have no link with them and in fact still want/need to pay a visit), these videos include reviews of starter set ups etc.
Hope this helps but be warned guitars can seriously damage your wealth, in the past 12 months I have gone from zero guitars to two acoustics and an electric and am now considering purchasing a fourth guitar and my first pedal, although my wife doesn't know yet.
P.S. I was very lucky as the amp was a freebie in exchange for a cable!
Good luck
