For the three-lane maps, I usually see middle lane being the solo lane, but it's easy to swap that around, and swapping lanes is much more common, especially when you get a kill in the 2v2 lanes and one of you goes off to gank the poor sod 1v1ing in the solo lane. This happens pretty much from the start of the match.
As long as one person's in each lane, you're not losing any XP, because it's all shared, which is what makes things more volatile, since you can go gank another lane without sacrificing team XP in your lane.
There's also Versus AI, but if you mean against other players, then yes. Versus AI is a good place to get a feel for heroes and to grind out the first few levels, getting their talents unlocked, before heading into pvp matches.
"Specialists" are heroes with slightly oddball mechanics. This doesn't mean they do less damage than Assassins; I tend to main Sgt. Hammer, who's a metric ton of damage-dealing. But Hammer's specialized mechanics make them less Assassin-y, and are why the hero's classed as a Specialist. It's a bit of a catchall of the heroes that don't fit the three main roles.
It goes pretty quick, honestly. I'm playing supercasually; I'm almost at player level 15. I've already bought Sgt. Hammer and Raynor with gold earned, and I've got about 5.5k saved up; I should be able to get another 7k hero next week.
Skins and such are expensive, but you can unlock heroes just fine without spending money. Early on, there's some big gold rewards in player levels. Once those run thin, you'll have unlocked Daily Quests, which are something like 300-800g, depending on the quest; you get one a day, and they often overlap (Play 8 games, Win 3 games, Play 3 games as Specialist, three I had earlier this week, three matches with Sgt. Hammer and I cleared two and was at 3/8 on the first).
Given the number of heroes available, too, the "free roster" will give you a good idea of what various heroes are like; I recommend trying a hero out before spending the gold. If they're not up this week, they should be there in a week or two, given the size of the roster. There's additional heros on the free roster that get unlocked at player levels 12 and 15, too; once you get there, you generally have a decent selection to pick from.
Biggest things to remember in HotS is that this is very much a team game; while you can 1v1 with a lot of heroes, it's usually near-impossible to 1v2 effectively, even with a level advantage. Also, map objectives are crucial. Unless you're getting that tower down or that hero killed in the next 5 seconds, break off and head for the objective if your team needs you there.
