Where is your location? USA? You can go to a pawn shop for the Amp, I got a Crate GX-65 for cheap and I have abuse the hell out of it, 10 yrs and still sounds nice, I like it so much that I bought a MX-120.
As for the guitar, the same applies, you can get a decent one if you know what you are looking for and you do your home work. One of those cheap kit guitars is OK, but soon you will feel that you did a bad choice and wished you had bought something better. I don't like the Epiphone from the ones that you posted, so my choice would be the Ibanez. As for the Yamaha, I have used a Pacifica, and I did not liked it a bit...
Keep in mind that the Ibanez on the Metal pack is made out of basswood, I made kelly out of it and it sounds good, but it is very soft so you can dind it very bad if you are not careful.
