Without wishing to be too snippy, until you get your processing sorted it doesn't matter what camera you're using, all your negatives will look like they've been left on a dancefloor for an evening.
That said, bear in mind SLRs are using 15-30 year old technology, and a slow zoom lens will only add to autofocus woes. A well set up manual film camera is as quick as anything out there, but I sometimes use a Canon 3000n with 40mm pancake lens. It's pretty quick and sharp, but next to useless with a zoom in all but brilliant light, and not fast even then. The main reason I use it is it fits in a pocket.
